    INTEGRAL DOMAINS WITH BOOLEAN t-CLASS SEMIGROUP S. KABBAJ AND A. MIMOUNI Abstract. The t-class semigroup of an integral domain is the semigroup of the isomorphy classes of the t-ideals with the operation induced by t- multiplication. This paper investigates integral domains with Boolean t-class semigroup with an emphasis on the GCD and stability conditions. The main results establish t-analogues for well-known results on Pr¨ufer domains and B´ezout domains of finite character. 1. Introduction All rings considered in this paper are integral domains (i.e., commutative with identity and without zero-divisors). The class semigroup of a domain R, denoted S(R), is the semigroup of nonzero fractional ideals modulo its subsemigroup of nonzero principal ideals [11, 41]. The t-class semigroup of R, denoted St(R), is the semigroup of fractional t-ideals modulo its subsemigroup of nonzero principal ideals, that is, the semigroup of the isomorphy classes of the t-ideals of R with the operation induced by ideal t-multiplication. Notice that St(R) is the t-analogue of S(R), as the class group Cl(R) is the t-analogue of the Picard group Pic(R). The following set-theoretic inclusions always hold: Pic(R) ⊆ Cl(R) ⊆ St(R) ⊆ S(R). Note that the first and third inclusions turn into equality for Pr¨ufer domains and the second does so for Krull domains. More details on these objects are provided in the next section. Divisibility properties of a domain R are often reflected in group or semigroup- theoretic properties of Cl(R) or S(R).

  • Characterization of Pr¨Ufer-Like Monoids and Domains by Gcd
    CHARACTERIZATION OF PRUFER-LIKE¨ MONOIDS AND DOMAINS BY GCD-THEORIES FRANZ HALTER-KOCH Abstract. We combine ideal-theoretic and divisor-theoretic methods to characterize various classes of Pr¨ufer-like monoids and domains by the gcd-properties of certain semi- groups of invertible ideals. 1. Introduction One of the main themes of multiplicative ideal theory during the last decades was the characterization and investigation of various classes of integral domains defined by the invertibility properties of certain classes of ideals. In this field, Pr¨uferdomains form the classical antetype, and there is a wealth of generalizations and variations of this concept in the literature. In this paper, we combine ideal-theoretic and divisor-theoretic methods to arrange some known characterizations of Pr¨ufer-like domains in a new way and to present several new ones. One of the basic ideas in our investigations is to address the gcd-properties of certain semigroups of invertible (integral) ideals and to combine this viewpoint with the concept of gcd-theories. Although the theory of integral domains is our main concern, the paper is written in the language of (commutative cancellative) monoids in order to point out the purely multiplicative character of the theory. The main results are the Theorems 3.4 and 3.5 and the subsequent theorems and corollaries. In Section 2 we gather the necessary results from the theory of monoid homomorphisms and ideal systems. 2. Monoids and homomorphisms Throughout this paper, by a monoid D we mean (deviating from the usual termi- nology) a commutative multiplicative semigroup with unit element 1 ∈ D and a zero element 0 ∈ D (satisfying 1x = x and 0x = 0 for all x ∈ D), and we always assume that D• = D \{0} is cancellative (that is, for all a, b ∈ D and c ∈ D•, if ac = bc, then a = b ).

  • Symmetric Coverage of Dynamic Mapping Error for Mobile Sensor Networks
    2011 American Control Conference on O'Farrell Street, San Francisco, CA, USA June 29 - July 01, 2011 Symmetric coverage of dynamic mapping error for mobile sensor networks Carlos H. Caicedo-Nu´nez˜ and Naomi Ehrich Leonard Abstract—We present an approach to control design for nonuniform density fields. Related problems include control a mobile sensor network tasked with sampling a scalar field of a mobile sensor network in a noisy, possibly time-varying and providing optimal space-time measurements. The coverage field for minimum-error spatial estimation [9], [10] and metric is derived from the mapping error in objective analysis (OA), an assimilation scheme that provides a linear statistical cooperative exploration of features [11]. In [12] agents are estimation of a sampled field. OA mapping error is an example deployed in a distributed way in order to maximize the of a consumable density field: the error decreases dynamically probability of event detection. The authors of [13] study the at locations where agents move and sample. OA mapping error distributed implementation of maximizing joint entropy in is also a regenerating density field if the sampled field is measurements. However, none of these methods have been time-varying: error increases over time as measurement value decays. The resulting optimal coverage problem presents a chal- designed to specifically address a spatial-temporal density lenge to traditional coverage methods. We prove a symmetric field that changes in response to the motion of the agents. dynamic coverage solution that exploits the symmetry of the In this paper we propose a coverage strategy for a density domain and yields symmetry-preserving coordinated motion field defined by OA mapping error in the case that the of mobile sensors.

  • A LOCALIZATION of R[X]
    Can. J. Math., Vol. XXXIII, No. 1, 1981, pp. 103-115 A LOCALIZATION OF R[x] JAMES A. HUCKABA AND IRA J. PAPICK 1. Introduction. Throughout this paper, R will be a commutative integral domain with identity and x an indeterminate. If / G R[x], let CR(J) denote the ideal of R generated by the coefficients of/. Define 1 SR = {/ G R[x]: cR(f) = R\ and UR = {/ G lî(s): ^(J)" = *}. For a,b £ R, write (a:6) = {r G R: rb G (a)}. When no confusion may result, we will write c(f),S, U, and (a:b). It follows that both 5 and U are multiplicatively closed sets in R[x] [7, Proposition 33.1], [17, Theorem F], and that R[x]s Q R[x]n. The ring R[x]s, denoted by R(x), has been the object of study of several authors (see for example [1], [2], [3], [12]). An especially inter­ esting paper concerning R(x) is that of Arnold's [3], where he, among other things, characterizes when R(x) is a Priifer domain. We shall make special use of his results in our work. In § 2 we determine conditions on the ring R so that R(x) = R[x]v. A complete characterization of this property is given for Noetherian domains in Proposition 2.2. In particular, we prove that if R is a Noe­ therian domain, then R(x) = R[x]v if and only if depth (R) ^ 1. Some sufficient conditions for R(x) = R[x]u are that R be treed (Proposition 2.5), or that SP (R) (see § 2 for définitions) be finite (Proposition 2.9).

  • Unique Factorization Domains in Commutative Algebra.Pdf (366.6Kb)
    Unique Factorization Domains in Commutative Algebra Yongjian Huang Advisor: Prof. Daniel Katz University of Kansas May 20, 2021 1 Introduction In this project, we learn about unique factorization domains in commutative algebra. Most importantly, we explore the relation between unique factorization domains and regular local rings, and prove the main theorem: If R is a regular local ring, so is a unique factorization domain. 2 Prime ideals Before learning the section about unique factorization domains, we first need to know about definition and theorems about prime ideals. Definition 2.1. In a commutative ring R, the ideal I is prime if ab 2 I implies a 2 I or b 2 I. Alternatively, I is prime if R=I is an integral domain. The following theorem tells us another way to define prime ideals. Theorem 2.1. Let S be a multiplicatively closed set in a ring R and let I be an ideal in R maximal with respect to the exclusion of S. Then I is prime. Proof. Given ab 2 I , we want to show a 2 I or b 2 I . We give a proof by contradiction, suppose a2 = I and b2 = I, then the ideal (I; a) generated by I and a is strictly larger than I. So the ideal (I; a) intersects S. Thus, there exists an element s 2 S of the form s1 = i1 + xa, where i1 2 I and x 2 R. Similarly, we have s2 = i2 + yb, where i2 2 I and y 2 R. s1 · s2 = (i1 + xa)(i2 + yb) = i1i2 + i1yb + i2xa + xyab Thus, s1s2 2 I.

    Unique-factorization domains MAT 347 NOTES ON UNIQUE FACTORIZATION DOMAINS Alfonso Gracia-Saz, MAT 347 Note: These notes summarize the approach I will take to Chapter 8. You are welcome to read Chapter 8 in the book instead, which simply uses a different order, and goes in slightly different depth at different points. If you read the book, notice that I will skip any references to universal side divisors and Dedekind-Hasse norms. If you find any typos or mistakes, please let me know. These notes complement, but do not replace lectures. Last updated on January 21, 2016. Note 1. Through this paper, we will assume that all our rings are integral domains. R will always denote an integral domains, even if we don't say it each time. Motivation: We know that every integer number is the product of prime numbers in a unique way. Sort of. We just believed our kindergarden teacher when she told us, and we omitted the fact that it needed to be proven. We want to prove that this is true, that something similar is true in the ring of polynomials over a field. More generally, in which domains is this true? In which domains does this fail? 1 Unique-factorization domains In this section we want to define what it means that \every" element can be written as product of \primes" in a \unique" way (as we normally think of the integers), and we want to see some examples where this fails. It will take us a few definitions. Definition 2. Let a; b 2 R.

  • Conglomerated Filters, Statistical Measures, and Representations by Ultrafilters
    CONGLOMERATED FILTERS, STATISTICAL MEASURES, AND REPRESENTATIONS BY ULTRAFILTERS VLADIMIR KADETS AND DMYTRO SELIUTIN Abstract. Using a new concept of conglomerated filter we demonstrate in a purely com- binatorial way that none of Erd¨os-Ulamfilters or summable filters can be generated by a single statistical measure and consequently they cannot be represented as intersections of countable families of ulrafilters. Minimal families of ultrafilters and their intersections are studied and several open questions are discussed. 1. Introduction In 1937, Henri Cartan (1904{2008), one of the founders of the Bourbaki group, introduced the concepts of filter and ultrafilter [3, 4]. These concepts were among the cornerstones of Bourbaki's exposition of General Topology [2]. For non-metrizable spaces, filter convergence is a good substitute for ordinary convergence of sequences, in particular a Hausdorff space X is compact if and only if every filter in X has a cluster point. We refer to [14, Section 16.1] for a brief introduction to filters and compactness. Filters and ultrafiters (or equivalent concepts of ideals and maximal ideals of subsets) are widely used in Topology, Model Theory, and Functional Analysis. Let us recall some definitions. A filter F on a set Ω 6= ; is a non-empty collection of subsets of Ω satisfying the following axioms: (a) ; 2= F; (b) if A; B 2 F then A \ B 2 F; (c) for every A 2 F if B ⊃ A then B 2 F. arXiv:2012.02866v1 [math.FA] 4 Dec 2020 The natural ordering on the set of filters on Ω is defined as follows: F1 F2 if F1 ⊃ F2.

It is continuously differentiable, i.e. 퐶1, if 휑′ exists and is continuous on [푎, 푏]. • An open set 푈 ⊆ C is path-connected if for every 푧, 푤 ∈ 푈 there exists a curve 휑 ∶ [0, 1] → 푈 with endpoints 푧, 푤.
