Torunbalcı Aydın ∗ aYildiz Technical University, Faculty of Chemical and Metallurgical Engineering, Department of Mathematical Engineering, Davutpasa Campus, 34220, Esenler, Istanbul,˙ TURKEY Abstract In the paper, we define the q-Fibonacci bicomplex quaternions and the q- Lucas bicomplex quaternions, respectively. Then, we give some algebraic properties of q-Fibonacci bicomplex quaternions and the q-Lucas bicomplex quaternions. Keywords: Bicomplex number; q-integer; Fibonacci number; Bicomplex Fibonacci quaternion; q-quaternion; q-Fibonacci quaternion. 1. Introduction The real quaternions were first described by Irish mathematician William Rowan Hamilton in 1843. The real quaternions constitute an extension of complex numbers into a four-dimensional space and can be considered as four-dimensional vectors, in the same way that complex numbers are consid- ered as two-dimensional vectors. Hamilton [1] introduced the set of quater- nions which can be represented as H = { q = q0 + i q1 + j q2 + k q3 | q0, q1, q2, q3 ∈ R } (1) where arXiv:2108.06351v1 [math.RA] 13 Aug 2021 i2 = j2 = k2 = −1 , i j = −j i = k, jk = −k j = i, ki = −i k = j . (2) Horadam [2, 3] defined complex Fibonacci and Lucas quaternions as follows Qn = Fn + Fn+1 i + Fn+2 j + Fn+3 k (3) ∗Corresponding author Email address: [email protected] (F. Torunbalcı Aydın) Preprint submitted to Chaos, Solitons & Fractals August 17, 2021 and Kn = Ln + Ln+1 i + Ln+2 j + Ln+3 k (4) where Fn and Ln denote the n−th Fibonacci and Lucas numbers, respectively. Also, the imaginary quaternion units ij, k have the following rules i2 = j2 = k2 = −1 , i j = −j i = k, jk = −k j = i, ki = −ik = j There are several studies on quaternions as the Fibonacci and Lucas quater- nions and their generalizations, for example,[4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]. Bicomplex numbers were introduced by Corrado Segre in 1892 [15]. In 1991, G. Baley Price, the bicomplex numbers are given in his book based on multi- complex spaces and functions [16]. In recent years, fractal structures of these numbers have also been studied [17, 18]. The set of bicomplex numbers can be expressed by the basis {1 ,i,j,ij } (Table 1) as, C2 = { q = q1 + i q2 + j q3 + i j q4 | q1, q2, q3, q4 ∈ R} (5) where i,j and i j satisfy the conditions i2 = −1, j2 = −1, i j = j i. (6) In 2018, the bicomplex Fibonacci quaternions defined by Aydın Torunbalcı [19] as follows BFn = Fn + i Fn+1 + j Fn+2 + i j Fn+3 (7) =(Fn + i Fn+1)+(Fn+2 + i Fn+3) j where i, j and i j satisfy the conditions (6). The theory of the quantum q-calculus has been extensively studied in many branches of mathematics as well as in other areas in biology, physics, electro- chemistry, economics, probability theory, and statistics [20, 21]. For n ∈ N0 , the q-integer [n]q is defined as follows n 1 − q 2 n 1 [n] = =1+ q + q + ... + q − . (8) q 1 − q m By (8), for all m, n ∈ Z, can be easily obtained [m + n]q = [m]q + q [n]q. For more details related to the quantum q-calculus, we refer to [22, 23]. 2 In 2019, q-Fibonacci hybrid and q-Lucas hybrid numbers defined by Kızılate¸s [24] as follows n 1 n1 n+1 HFn(α; q)=α − [n]q + α [n + 1]q i + α [n + 2]q ε n+2 (9) + α [n + 3]q h and [2 n] [2 n + 2] [2 n + 4] HL (α; q)=αn q + αn+1 q i + αn+2 q ε n [n] [n + 1] [n + 2] q q q (10) [2 n + 6] + αn+3 q h [n + 3]q where i, ε and h satisfy the conditions 2 2 2 i = −1, ε =0, h =1, i h = h i = ε + i. (11) Also, Kızılate¸sderived several interesting properties of these numbers such as Binet-Like formulas, exponential generating functions, summation formu- las, Cassini-like identities, Catalan-like identities and d’Ocagne-like identities [24]. 2. q-Fibonacci bicomplex quaternions In this section, we define q-Fibonacci bicomplex quaternions and q-Lucas bicomplex quaternions by using the basis {1,i,j,ij}, where i, j and i j satisfy the conditions (6) as follows n 1 n n+1 n+2 BFn(α; q)= α − [n]q + α [n + 1]q i + α [n + 2]q j + α [n + 3]q i j n 1 qn n+1 1 qn+1 = α ( α−αq )+ α ( α− αq ) i − − n+2 1 qn+2 n+3 1 qn+3 +α ( α− αq ) j + α ( α− αq ) i j − − αn 2 3 = α (αq) [1+ α i + α j + α i j ] − n (αq) 2 3 − α (αq) [1+(α q) i +(α q) j +(α q) i j ] − (12) 3 and n [2 n]q n+1 [2 n+2]q n+2 [2 n+4]q n+3 [2 n+6]q BLn(α; q)= α + α i + α j + α i j [n]q [n+1]q [n+2]q [n+3]q 2n 1 q2n 2n+2 1 q2n+2 = α ( αn −(αq)n )+ α ( αn+1− (αq)n+1 ) i − − 2n+4 1 q2n+4 2n+6 1 q2n+6 +α ( αn+2− (αq)n+2 ) j + α ( αn+3− (αq)n+3 ) i j − − = αn (1 + α i + α2 j + α3 i j ) −(α q)n (1+(α q) i +(α q)2 j +(α q)3 i j ) (13) 1+√5 1 BF For α = 2 and (α q)= −α , q-Fibonacci bicomplex quaternion n(α; q) become the bicomplex Fibonacci quaternions BFn. The addition, substraction and multiplication by real scalars of two q-Fibonacci bicomplex quaternions gives q-Fibonacci bicomplex quaternion. Then, the addition, subtraction and multiplication by scalar of q-Fibonacci bicomplex quaternions are defined by n 1 n n+1 BFn(α; q) ± BFm(α; q)= (α − [n]q + α [n + 1]q i + α [n + 2]q j n+2 +α [n + 3]q i j) m 1 m m+1 ±(α − [m]q + α [m + 1]q i + α [m + 2]q j m+2 +α [m + 3]q i j) n 1 qn m 1 qm = [α ( α−αq ) ± α ( α−αq )] n+1− 1 qn+1 −m+1 1 qm+1 +[α ( α− αq ) ± α ( α− αq )] i n+2 1 −qn+2 m+2 1 −qm+2 +[α ( α− αq ) ± α ( α− αq )] j n+3 1 −qn+3 m+3 1 −qm+3 +[α ( α− αq ) ± α ( α− αq )] i j 1 n− m − 2 3 = α αq { (α ± α )(1 + α i + α j + α i j) +((− α q)n ± (α q)m )(1+(α q) i +(α q)2 j +(α q)3 i j ) }. (14) The multiplication of q-Fibonacci bicomplex quaternion by the real scalar λ is defined as λ BF (α; q) = λαn(1 + α i + α2 j + α3 i j ) n (15) +λ (α q)n (1+(α q) i +(α q)2 j +(α q)3 i j ). 4 The scalar and the vector part of BFn(α; q) which is the n − th term of the q-Fibonacci bicomplex quaternion are denoted by n 1 n n+1 n+2 SBFn(α;q) = α − [n]q, VBFn(α;q) = α [n + 1]q i+α [n + 2]q j+α [n + 3]q i j. (16) Thus, the q-Fibonacci bicomplex quaternion BFn(α; q) is given by BF n(α; q)= SBFn(α;q) + VBFn(α;q) . The multiplication of two q-Fibonacci bicomplex quaternions is defined by n 1 n n+1 BFn(α; q) × BFm(α; q)= (α − [n]q + α [n + 1]q i + α [n + 2]q j n+2 +α [n + 3]q i j) m 1 m m+1 × (α − [m]q + α [m + 1]q i + α [m + 2]q j m+2 +α [m + 3]q i j) 1 n+m 2 4 6 = α αq (α ) { (1 − α − α + α ) +2− i (α − α5)+2 j (α2 − α4)+4 i j (α3)} −qm {(1 − α(α q) − α2(α q)2 + α3(α q)3) +i (α +(α q) − α2(α q)3 − α3(α q)2) +j (α2 +(α q)2 − α(α q)3 − α3(α q)) +i j (α3 +(α q)3 − α(α q)2 − α2(α q))} −qn {(1 − α(α q) − α2(α q)2 + α3(α q)3) +i (α +(α q) − α2(α q)3 − α3(α q)2) +j (α2 +(α q)2 − α(α q)3 − α3(α q)) +i j (α3 +(α q)3 + α2(α q)+ α(α q)2)} +qn+m {(1 − (α q)2 − (α q)4 +(α q)6) +2 i ((α q) − (α q)5)+2 j ((α q)2 − (α q)4) +4 i j ((α q)3 )} = BFm(α; q) × BFn(α; q) (17) Here, quaternion multiplication is done using bicomplex quaternionic units (table 1), and this product is commutative. Also, the q-Fibonacci bicomplex quaternion product may be obtained as follows 5 Table 1: Multiplication scheme of bicomplex units x 1 i j ij 1 1 i j ij i i −1 i j −j j j ij −1 −i ij ij −j −i 1 BFn(α; q) × BFm(α; q)= n−1 n n+1 n+2 m−1 α [n]q α [n + 1]q α [n + 2]q α [n + 3]q α [m]q n − n−1 − n+2 n+1 m α [n + 1]q α [n]q α [n + 3]q α [n + 2]q α [m + 1]q n+1 −n+2 − n−1 − n .

  • Hypercomplex Algebras and Their Application to the Mathematical
    Hypercomplex Algebras and their application to the mathematical formulation of Quantum Theory Torsten Hertig I1, Philip H¨ohmann II2, Ralf Otte I3 I tecData AG Bahnhofsstrasse 114, CH-9240 Uzwil, Schweiz 1 [email protected] 3 [email protected] II info-key GmbH & Co. KG Heinz-Fangman-Straße 2, DE-42287 Wuppertal, Deutschland 2 [email protected] March 31, 2014 Abstract Quantum theory (QT) which is one of the basic theories of physics, namely in terms of ERWIN SCHRODINGER¨ ’s 1926 wave functions in general requires the field C of the complex numbers to be formulated. However, even the complex-valued description soon turned out to be insufficient. Incorporating EINSTEIN’s theory of Special Relativity (SR) (SCHRODINGER¨ , OSKAR KLEIN, WALTER GORDON, 1926, PAUL DIRAC 1928) leads to an equation which requires some coefficients which can neither be real nor complex but rather must be hypercomplex. It is conventional to write down the DIRAC equation using pairwise anti-commuting matrices. However, a unitary ring of square matrices is a hypercomplex algebra by definition, namely an associative one. However, it is the algebraic properties of the elements and their relations to one another, rather than their precise form as matrices which is important. This encourages us to replace the matrix formulation by a more symbolic one of the single elements as linear combinations of some basis elements. In the case of the DIRAC equation, these elements are called biquaternions, also known as quaternions over the complex numbers. As an algebra over R, the biquaternions are eight-dimensional; as subalgebras, this algebra contains the division ring H of the quaternions at one hand and the algebra C ⊗ C of the bicomplex numbers at the other, the latter being commutative in contrast to H.

  • On Some Matrix Representations of Bicomplex Numbers

We examined the matrix representa- tions and algebraic properties of these numbers. We also computed the eigenvalues and eigenvectors of these particular matrices. Keywords: Bicomplex numbers, Recurrences, Fibonacci sequence. 2010 Mathematics Subject Classification: 11B39;11B37;11R52. 1. Introduction Quaternions and bicomplex numbers are defined as a generalization of the complex numbers. BC, which is a set of bicomplex numbers, is defined as 2 BC = fz1 + z2jj z1;z2 2 C; j = −1g; (1.1) where C is the set of complex numbers with the imaginary unit i, also i and i 6= j are commuting imaginary units. Bicomplex numbers are a recent powerful mathematical tool to develop the theories of functions and play an important role in solving problems of electromagnetism. These numbers are also advantageous than quaternions due to the commutative property. In BC, multiplication is commutative, associative and distributive over addition and BC is a commutative algebra but not division algebra. Any element b in BC is written, for t = 1;2;3;4 and at 2 R, as b = a11 + a2i + a3j + a4ij. Addition, multiplication and division can be done term by term and it is helpful to understand the structure of functions of a bicomplex variable.

Introduction In this paper, we define bicomplex Tetranacci and bicomplex Tetranacci-Lucas quaternions by combining bicomplex numbers and Tetranacci, Tetranacci-Lucas numbers and give some properties of them. Before giving their definition, we present some information on bicomplex numbers and also on Tetranacci and Tetranacci-Lucas numbers. The bicomplex numbers (quaternions) are defined by the four bases elements 1; i; j; ij where i; j and ij satisfy the following properties: i2 = −1; j2 = −1; ij = ji: A bicomplex number can be expressed as follows: q = a0 + ia1 + ja2 + ija3 = (a0 + ia1) + j(a2 + ia3) = z0 + jz1 where a0; a1; a2; a3 are real numbers and z0; z1 are complex numbers.

  • Stability Conditions of Bicomplex-Valued Hopfield Neural Networks
    LETTER Communicated by Marcos Eduardo Valle Stability Conditions of Bicomplex-Valued Hopfield Neural Networks Masaki Kobayashi Downloaded from http://direct.mit.edu/neco/article-pdf/33/2/552/1896796/neco_a_01350.pdf by guest on 30 September 2021 [email protected] Mathematical Science Center, University of Yamanashi, Kofu, Yamanashi 400-8511, Japan Hopfield neural networks have been extended using hypercomplex num- bers. The algebra of bicomplex numbers, also referred to as commutative quaternions, is a number system of dimension 4. Since the multiplica- tion is commutative, many notions and theories of linear algebra, such as determinant, are available, unlike quaternions. A bicomplex-valued Hopfield neural network (BHNN) has been proposed as a multistate neu- ral associative memory. However, the stability conditions have been in- sufficient for the projection rule. In this work, the stability conditions are extended and applied to improvement of the projection rule. The com- puter simulations suggest improved noise tolerance. 1 Introduction A Hopfield neural network (HNN) is an associative memory model using neural networks (Hopfield, 1984). It has been extended to a complex-valued HNN (CHNN), a multistate associative memory model that is useful for storing multilevel data (Aoki & Kosugi, 2000; Aoki, 2002; Jankowski, Lo- zowski, & Zurada, 1996; Muezzinoglu, Guzelis, & Zurada, 2003; Tanaka & Aihara, 2009; Zheng, 2014). Moreover, a CHNN has been extended using hypercomplex numbers (Kuroe, Tanigawa, & Iima, 2011; Kobayashi, 2018a, 2019). The algebra of hyperbolic numbers is a number system of dimen- sion 2, like that of complex numbers. Several models of hyperbolic HNNs (HHNNs) have been proposed. An HHNN using a directional activation function is an alternative of CHNN and improves noise tolerance.

In 2015, Ramirez [3] defined the the k-Fibonacci and the k-Lucas quaternions as follows: Dk;n =fFk;n + iFk;n+1 + j Fk;n+2 + kFk;n+3 j Fk;n; n −th k-Fibonacci numberg; and Pk;n =fLk;n + iLk;n+1 + j Lk;n+2 + kLk;n+3 j Lk;n; n −th k-Lucas numberg where i, j and k satisfy the multiplication rules i2 = j2 = k2 = −1; i j = −ji = k; j k = −kj = i; k i = −ik = j: In 1892, bicomplex numbers were introduced by Corrado Segre, for the first time [4].

  • “Congeneric Surd Equations” to “Segre's Bicomplex Numbers”
    From the theory of “congeneric surd equations” to “Segre’s bicomplex numbers” CINZIA CERRONI1 Abstract: We will study the historical pathway of the emergence of Tessarines or Bicomplex numbers, from their origin as “imaginary” solutions of irrational equations, to their insertion in the context of study of the algebras of hypercomplex numbers. MSC-class: 01A55, 08-03, 51-03. Keywords: James Cockle; William Rowan Hamilton; Corrado Segre; Tessarines; Biquaternions; Bicomplex numbers. 1. Introduction Beginning from the end of the first half of the nineteenth century, particularly in Great Britain, in the wake of researches on geometrical interpretation of complex numbers, studies developed that led to the birth of new systems of hypercomplex numbers and are at the basis of the birth of modern algebra. In particular, the discovery in 1843 of Quaternions by William Rowan Hamilton (1805-1865) revealed to mathematicians the existence of an algebraic system that had all the properties of real and complex numbers except commutativity of multiplication. Further, the studies on symbolic algebra2 by George Peacock (1791-1858) and on logic by Augustus De Morgan (1806-1871) created a context of reflection and analysis on the laws of arithmetic and their meaning. As a result, researches were carried out in Great Britain on new systems of hypercomplex numbers, leading to the discovery of Octonions (1843/1845) by John T. Graves (1806-1870) and Arthur Cayley (1821-1895), of the theory of Pluriquaternions3 (1848) by Thomas Penyngton Kirkman (1806-1895), of Biquaternions (1873) and the Algebras (1878) of William Kingdon Clifford (1845-1879) and to the systematic presentation of the algebras of hypercomplex numbers (1870), known until that time, through the work of Benjamin Peirce (1809-1880).

  • Note on Bicomplex Matrices
    MATHEMATICAL SCIENCES AND APPLICATIONS E-NOTES 6 (2)46-56 (2018) c MSAEN Note on Bicomplex Matrices Canan Ölçek and Semra Kaya Nurkan* (Communicated by Bülent ALTUNKAYA) Abstract In this paper, we consider bicomplex numbers and bicomplex matrices. Firstly, we give some properties of bicomplex numbers.After that we investigate bicomplex matrices using properties of complex ma- trices.Then we define the complex adjoint matrix of bicomplex matrices and we describe some of their properties. Furthermore, we give the definition of q-determinant of bicomplex matrices. Keywords: Complex number; Bicomplex number; Complex matrix; Bicomplex matrix. AMS Subject Classification (2010): 15B33; 11E88; 11R52. *Corresponding author 1. Introduction The subject of multiple imaginary units was examined in the 1840s. In a long series "On quaternions; or on a new system of imaginaries in algebra" beginning in 1844 in Philosophical Magazine, William Rowan Hamilton communicated a system multiplying according to the quaternion group. In 1848 Thomas Kirkman reported on his correspondence with Arthur Cayley regarding equations on the units determining a system of hypercomplex numbers. It is possible to arrive to bicomplex numbers by means of purely algebraic considerations. For example, if in a complex number a + ib we replace the real numbers a and b by complex numbers z1 = a1 + ia2 and z2 = b1 + ib2, then we get just another complex number: z1 + iz2 = (a1 + ia2) + i(b1 + ib2) = (a1 − b2) + i(a2 + b1): If we want to obtain a new type of number, then we must use another imaginary unit, say j, with j2 = −1, and set z1 + jz2 = (a1 + ia2) + j(b1 + ib2) which gives a new object, outside the field of complex numbers.

    Conformal numbers S. Ulrych Wehrenbachhalde 35, CH-8053 Z¨urich, Switzerland Abstract The conformal compactification is considered in a hierarchy of hypercomplex pro- jective spaces with relevance in physics including Minkowski and Anti-de Sitter space. The geometries are expressed in terms of bicomplex Vahlen matrices and further broken down into their structural components. The relation between two subsequent projective spaces is displayed in terms of the complex unit and three additional hypercomplex numbers.

Introduction The complex numbers are central for the representation of physical processes in terms of mathematical models. However, they cannot cover all aspects alone and generalizations are necessary. One of the possible generalizations with po- tentially underestimated relevance in physics is the bicomplex number system [1, 2, 3, 4, 5]. Recent investigations in this area have been provided for example by [6, 7, 8, 9, 10]. The number system is also known under the name of Segre num- bers [11]. The bicomplex numbers coincide with the combination of hyperbolic and complex numbers formed by two commutative imaginary units, i √ 1 ≡ − and j √+1. The hyperbolic unit carries here the second complex number of ≡ arXiv:1705.07737v1 [math.GM] 18 May 2017 the bicomplex number system. More details on hyperbolic numbers have been provided beside many other authors by Yaglom [12], Sobczyk [13], Gal [14], or in correspondence with the bicomplex numbers by Rochon and Shapiro [15].
