  • Hasse Principles for Higher-Dimensional Fields 3
    Annals of Mathematics 183 (2016), 1{71 http://dx.doi.org/10.4007/annals.2016.183.1.1 Hasse principles for higher-dimensional fields By Uwe Jannsen dedicated to J¨urgen Neukirch Abstract For rather general excellent schemes X, K. Kato defined complexes of Gersten-Bloch-Ogus type involving the Galois cohomology groups of all residue fields of X. For arithmetically interesting schemes, he developed a fascinating web of conjectures on some of these complexes, which generalize the classical Hasse principle for Brauer groups over global fields, and proved these conjectures for low dimensions. We prove Kato's conjecture over number fields in any dimension. This gives a cohomological Hasse principle for function fields F over a number field K, involving the corresponding function fields Fv over the completions Kv of K. For global function fields K we prove the part on injectivity for coefficients invertible in K. Assuming resolution of singularities, we prove a similar conjecture of Kato over finite fields, and a generalization to arbitrary finitely generated fields. Contents 0. Introduction1 1.

  • Lesson 2: the Multiplication of Polynomials
    NYS COMMON CORE MATHEMATICS CURRICULUM Lesson 2 M1 ALGEBRA II Lesson 2: The Multiplication of Polynomials Student Outcomes . Students develop the distributive property for application to polynomial multiplication. Students connect multiplication of polynomials with multiplication of multi-digit integers. Lesson Notes This lesson begins to address standards A-SSE.A.2 and A-APR.C.4 directly and provides opportunities for students to practice MP.7 and MP.8. The work is scaffolded to allow students to discern patterns in repeated calculations, leading to some general polynomial identities that are explored further in the remaining lessons of this module. As in the last lesson, if students struggle with this lesson, they may need to review concepts covered in previous grades, such as: The connection between area properties and the distributive property: Grade 7, Module 6, Lesson 21. Introduction to the table method of multiplying polynomials: Algebra I, Module 1, Lesson 9. Multiplying polynomials (in the context of quadratics): Algebra I, Module 4, Lessons 1 and 2. Since division is the inverse operation of multiplication, it is important to make sure that your students understand how to multiply polynomials before moving on to division of polynomials in Lesson 3 of this module. In Lesson 3, division is explored using the reverse tabular method, so it is important for students to work through the table diagrams in this lesson to prepare them for the upcoming work. There continues to be a sharp distinction in this curriculum between justification and proof, such as justifying the identity (푎 + 푏)2 = 푎2 + 2푎푏 + 푏 using area properties and proving the identity using the distributive property.

  • Conics Over Function Fields and the Artin-Tate Conjecture José Felipe
    Conics over function fields and the Artin-Tate conjecture Jos´eFelipe Voloch Abstract: We prove that the Hasse principle for conics over function fields is a simple consequence of a provable case of the Artin-Tate conjecture for surfaces over finite fields. Hasse proved that a conic over a global field has a rational point if and only if it has points over all completions of the global field, an instance of the so-called local-global or Hasse principle. The case of the rational numbers is an old result of Legendre, who gave an elementary proof and a similar proof can be given in the case of rational functions over a finite field. Hasse’s proof, on the other hand, is a consequence of a more general result in Class Field Theory, the Hasse norm theorem. One purpose of this paper is to give a new proof of the local-global principle for conics over function fields, as a relatively simple consequence of a provable case of the Artin-Tate conjecture for surfaces over finite fields. This proof might be more complicated overall, once the work on the Artin-Tate conjecture is factored in, but it might be worthwhile recording since it suggests a new approach to local-global principles which might work in other contexts, such as number fields or higher dimensions. We also deduce from the Artin-Tate conjecture, together with a recent result [LLR] on Brauer groups, the Hilbert reciprocity law. We also do a careful study of conic bundles over curves over finite fields which might have independent interest.

  • Counterexamples to the Hasse Principle
    COUNTEREXAMPLES TO THE HASSE PRINCIPLE W. AITKEN AND F. LEMMERMEYER Abstract. This article explains the Hasse principle and gives a self-contained development of certain counterexamples to this principle. The counterexam- ples considered are similar to the earliest counterexample discovered by Lind and Reichardt. This type of counterexample is important in the theory of elliptic curves: today they are interpreted as nontrivial elements in Tate– Shafarevich groups. 1. Introduction In this article we develop counterexamplestotheHasseprincipleusingonlytech- niques from undergraduate number theory and algebra. By keeping the technical prerequisites to a minimum, we hope to provide a path for nonspecialists to this interesting area of number theory. The counterexamples considered here extend the classical counterexample of Lind and Reichardt. As discussed in an appendix, such counterexamples are important in the theory of elliptic curves, and today are interpreted as nontrivial elements in Tate–Shafarevich groups. 2. Background The problem of determining if the Diophantine equation aX2 + bY 2 + cZ2 =0 (1) has nontrivial solutions with values in Z has played a prominent role in the history of number theory. We assume that a, b, and c are nonzero integers and, using a simple argument, we reduce to the case where the product abc is square-free. Lagrange (1768) solved the problem by giving a descent procedure which determines in a finite number of steps whether or not (1) has a nontrivial Z-solution, but Legendre (1788) gave the definitive solution. Legendre proved that the following conditions, known by Euler to be necessary, are sufficient for the existence of a nontrivial Z- solution: (i) a, b,andc do not all have the same sign, and (ii) ab is a square modulo c , ca is a square modulo b ,and bc is a square modulo− a .

  • Algebraic Tori — Thirty Years After
    ALGEBRAIC TORI | THIRTY YEARS AFTER BORIS KUNYAVSKI˘I To my teacher Valentin Evgenyevich Voskresenski˘ı, with gratitude and admiration This article is an expanded version of my talk given at the Interna- tional Conference \Algebra and Number Theory" dedicated to the 80th anniversary of V. E. Voskresenski˘ı, which was held at the Samara State University in May 2007. The goal is to give an overview of results of V. E. Voskresenski˘ı on arithmetic and birational properties of algebraic tori which culminated in his monograph [Vo77] published 30 years ago. I shall try to put these results and ideas into somehow broader context and also to give a brief digest of the relevant activity related to the period after the English version of the monograph [Vo98] appeared. 1. Rationality and nonrationality problems A classical problem, going back to Pythagorean triples, of describing the set of solutions of a given system of polynomial equations by ratio- nal functions in a certain number of parameters (rationality problem) has been an attraction for many generations. Although a lot of various techniques have been used, one can notice that after all, to establish rationality, one usually has to exhibit some explicit parameterization such as that obtained by stereographic projection in the Pythagoras problem. The situation is drastically different if one wants to estab- lish non-existence of such a parameterization (nonrationality problem): here one usually has to use some known (or even invent some new) bi- rational invariant allowing one to detect nonrationality by comparing its value for the object under consideration with some \standard" one known to be zero; if the computation gives a nonzero value, we are done.

  • Chapter 2. Multiplication and Division of Whole Numbers in the Last Chapter You Saw That Addition and Subtraction Were Inverse Mathematical Operations
    Chapter 2. Multiplication and Division of Whole Numbers In the last chapter you saw that addition and subtraction were inverse mathematical operations. For example, a pay raise of 50 cents an hour is the opposite of a 50 cents an hour pay cut. When you have completed this chapter, you’ll understand that multiplication and division are also inverse math- ematical operations. 2.1 Multiplication with Whole Numbers The Multiplication Table Learning the multiplication table shown below is a basic skill that must be mastered. Do you have to memorize this table? Yes! Can’t you just use a calculator? No! You must know this table by heart to be able to multiply numbers, to do division, and to do algebra. To be blunt, until you memorize this entire table, you won’t be able to progress further than this page.

  • Grade 7/8 Math Circles the Scale of Numbers Introduction
    Faculty of Mathematics Centre for Education in Waterloo, Ontario N2L 3G1 Mathematics and Computing Grade 7/8 Math Circles November 21/22/23, 2017 The Scale of Numbers Introduction Last week we quickly took a look at scientific notation, which is one way we can write down really big numbers. We can also use scientific notation to write very small numbers. 1 × 103 = 1; 000 1 × 102 = 100 1 × 101 = 10 1 × 100 = 1 1 × 10−1 = 0:1 1 × 10−2 = 0:01 1 × 10−3 = 0:001 As you can see above, every time the value of the exponent decreases, the number gets smaller by a factor of 10. This pattern continues even into negative exponent values! Another way of picturing negative exponents is as a division by a positive exponent. 1 10−6 = = 0:000001 106 In this lesson we will be looking at some famous, interesting, or important small numbers, and begin slowly working our way up to the biggest numbers ever used in mathematics! Obviously we can come up with any arbitrary number that is either extremely small or extremely large, but the purpose of this lesson is to only look at numbers with some kind of mathematical or scientific significance. 1 Extremely Small Numbers 1. Zero • Zero or `0' is the number that represents nothingness. It is the number with the smallest magnitude. • Zero only began being used as a number around the year 500. Before this, ancient mathematicians struggled with the concept of `nothing' being `something'. 2. Planck's Constant This is the smallest number that we will be looking at today other than zero.

His unexpected death came as a tremendous shock to all who knew him. There had not been any danger signals. It was hard to realize that a person of such strong vitality was gone, that such a great mind had been extinguished by a physical failure of the body. Artin was born in Vienna on March 3,1898. He grew up in Reichen- berg, now Tschechoslovakia, then still part of the Austrian empire. His childhood seems to have been lonely. Among the happiest periods was a school year which he spent in France. What he liked best to remember was his enveloping interest in chemistry during his high school days. In his own view, his inclination towards mathematics did not show before his sixteenth year, while earlier no trace of mathe­ matical aptitude had been apparent.1 I have often wondered what kind of experience it must have been for a high school teacher to have a student such as Artin in his class. During the first world war, he was drafted into the Austrian Army. After the war, he studied at the University of Leipzig from which he received his Ph.D. in 1921. He became "Privatdozent" at the Univer­ sity of Hamburg in 1923.

  • Cohomological Hasse Principle and Motivic Cohomology for Arithmetic Schemes
    COHOMOLOGICAL HASSE PRINCIPLE AND MOTIVIC COHOMOLOGY FOR ARITHMETIC SCHEMES by MORITZ KERZ and SHUJI SAITO ABSTRACT In 1985 Kazuya Kato formulated a fascinating framework of conjectures which generalizes the Hasse principle for the Brauer group of a global field to the so-called cohomological Hasse principle for an arithmetic scheme X. In this paper we prove the prime-to-characteristic part of the cohomological Hasse principle. We also explain its implications on finiteness of motivic cohomology and special values of zeta functions.

  • Counterexamples to the Local-Global Principle for Non-Singular Plane Curves and a Cubic Analogue of Ankeny-Artin-Chowla-Mordell Conjecture
    COUNTEREXAMPLES TO THE LOCAL-GLOBAL PRINCIPLE FOR NON-SINGULAR PLANE CURVES AND A CUBIC ANALOGUE OF ANKENY-ARTIN-CHOWLA-MORDELL CONJECTURE YOSHINOSUKE HIRAKAWA AND YOSUKE SHIMIZU Abstract. In this article, we introduce a systematic and uniform construction of non- singular plane curves of odd degrees n ≥ 5 which violate the local-global principle. Our construction works unconditionally for n divisible by p2 for some odd prime number p. Moreover, our construction also works for n divisible by some p ≥ 5 which satisfies 1=3 1=3 a conjecture on p-adic properties of the fundamental units of Q(p ) and Q((2p) ). This conjecture is a natural cubic analogue of the classical Ankeny-Artin-Chowla-Mordell 1=2 conjecture for Q(p ) and easily verified numerically. 1. Introduction In the theory of Diophantine equations, the local-global principle for quadratic forms established by Minkowski and Hasse is one of the major culminations (cf. [31, Theorem 8, Ch. IV]). In contrast, there exist many homogeneous forms of higher degrees which violate the local-global principle (i.e., counterexamples to the local-global principle). For example, Selmer [30] found that a non-singular plane cubic curve defined by (1) 3X3 + 4Y 3 = 5Z3 has rational points over R and Qp for every prime number p but not over Q. From eq. (1), we can easily construct reducible (especially singular) counterexamples of higher degrees. After that, Fujiwara [13] found that a non-singular plane quintic curve defined by (2) (X3 + 5Z3)(X2 + XY + Y 2) = 17Z5 violates the local-global principle. More recently, Cohen [9, Corollary 6.4.11] gave several p p p counterexamples of the form x + by + cz = 0 of degree p = 3; 5; 7; 11 with b; c 2 Z, and Nguyen [23, 24] gave recipes for counterexamples of even degrees and more complicated forms.

  • The Notion Of" Unimaginable Numbers" in Computational Number Theory
    Beyond Knuth’s notation for “Unimaginable Numbers” within computational number theory Antonino Leonardis1 - Gianfranco d’Atri2 - Fabio Caldarola3 1 Department of Mathematics and Computer Science, University of Calabria Arcavacata di Rende, Italy e-mail: [email protected] 2 Department of Mathematics and Computer Science, University of Calabria Arcavacata di Rende, Italy 3 Department of Mathematics and Computer Science, University of Calabria Arcavacata di Rende, Italy e-mail: [email protected] Abstract Literature considers under the name unimaginable numbers any positive in- teger going beyond any physical application, with this being more of a vague description of what we are talking about rather than an actual mathemati- cal definition (it is indeed used in many sources without a proper definition). This simply means that research in this topic must always consider shortened representations, usually involving recursion, to even being able to describe such numbers. One of the most known methodologies to conceive such numbers is using hyper-operations, that is a sequence of binary functions defined recursively starting from the usual chain: addition - multiplication - exponentiation. arXiv:1901.05372v2 [cs.LO] 12 Mar 2019 The most important notations to represent such hyper-operations have been considered by Knuth, Goodstein, Ackermann and Conway as described in this work’s introduction. Within this work we will give an axiomatic setup for this topic, and then try to find on one hand other ways to represent unimaginable numbers, as well as on the other hand applications to computer science, where the algorith- mic nature of representations and the increased computation capabilities of 1 computers give the perfect field to develop further the topic, exploring some possibilities to effectively operate with such big numbers.
