Equivalence Relations - Mathematical and Statistical Sciences
www-math.ucdenver.eduModular Arithmetic Theorem: For any natural number m, the modular relation ≡ m is an equivalence relation on ℤ. Pf: For any x in ℤ, since x – x = 0 and m | 0, x ≡ m x. (Reflexitivity) If x ≡ m y then m | x – y. Since y – x = -(x-y), m | y – x, and so, y ≡ m x. (Symmetry) If x ≡ m y and y ≡ m z then m | x – y and m | y ...
The Euclidean Algorithm and Multiplicative Inverses
www.math.utah.eduthinking about finding multiplicative inverses in modular arithmetic, but it turns out that if you look at his algorithm in reverse, that’s exactly what it does! The Euclidean Algorithm makes repeated used of integer division ideas: We “know” that if a and b are positive integers, then we may write a b = q + r b
Practice problems for the Math Olympiad - Texas A&M ...
www.tamug.eduModular Arithmetic means recycling of integers when they reach a fixed value, e.g., a 12 hour clock. or integers a, b, n, we write a=b(mod n), read “a is congruent to b modulo n”, if a-b is a multiple of n. e.g., 38=14(mod 12) because 38 -14 = 24 =2*12. Solution: For this question, we can solve it by finding all solutions and proving there ...
Cryptography: An Introduction (3rd Edition)
www.cs.umd.edu(modular arithmetic) and a little probability before. In addition, they would have at some point done (but probably forgotten) elementary calculus. Not that one needs calculus for cryptography, but the ability to happily deal with equations and symbols is certainly helpful. Apart from that I introduce everything needed from scratch.
Introduction to Shimura Varieties - James Milne
www.jmilne.orgThe arithmetic properties of elliptic modular functions and forms were extensively studied in the 1800s, culminating in the beautiful Kronecker Jugendtraum. Hilbert emphasized the importance of extending this theory to functions of several variables in the twelfth of his famous problems at the International Congress in 1900.

Abelian Varieties - James Milne
www.jmilne.orgThese notes are an introduction to the theory of abelian varieties, including the arithmetic of abelian varieties and Faltings’s proof of certain finiteness theorems. The orginal version of the notes was distributed during the teaching of an advanced graduate course. Alas, the notes are still in very rough form. BibTeX information @misc{milneAV,
