  • Introduction Modular Arithmetic Appendices
  • Programming Notes References Glossary
  • Introduction
    This document is a gentle introduction to computational number theory. The plan of the paper is to first give a quick overview of arithmetic in the modular integers. Throughout, we will emphasize computation and practical results rather than delving into the why. Simple programs, generally in JavaScript, are available for all of the algorithms mentioned. At the end of the paper we will introduce a the Gaussian Integers and Galois Fields and compare them to the modular integers. Companion papers will examine number theory from a more advanced perspective.
    Modular Arithmetic
    Modular arithmetic is arithmetic using integers modulo some fixed integer N . Thus, some examples of operations modulo 12 are:
    • 7 + 7 = 14 = 2 (mod 12) 5 * 7 = 35 = 11 (mod 12)
    Further examples can be generated and checked out with the following short programs. Note that, as JavaScript cannot compute with integers larger than 20 digits, the largest modulus allowed is 10 digits. (mod
    (mod
    Among the basic operations we have missed the division operator. If we were working in the integers we would almost never be able to define a quotient (unless the answer is itself an integer). In the modular integers we can often, but not always, define a quotient:

    Number Theory Staff Research during the last few years concerned problems in different branches of number theory which will be reviewed in the order adopted by Mathematical Reviews. In elementary number theory a problem (proposed by T. Cochrane and G. Meyerson) concerning covering systems of congruences has been solved in [10] and another one (proposed by W. Narkiewicz) concerning arithmetical functions in [14]. Various problems concerning generalized pseudoprimes have been solved in [1]-[4] and a problem on this subject proposed by C. Pomerance has been solved by A. Rotkiewicz (as yet unpublished). A criterion for reducibility over the rationals of the non-cyclotomic kernel of a non-reciprocal lacunary polynomial has been given by A. Schinzel (as yet unpublished). In diophantine equations, [8] gives a solution to Problem D16 from the book of R. Guy "Unsolved Problems in Number Theory" and [15] solves a problem on Pythagorean triangles proposed by I. Korec. [16] deals with a Diophantine equation related to generalized Bernoulli numbers. In the metric theory of algorithms a problem of M. Deleglise concerning continued fractions has been solved in [13].

    Summary
    The conference is open to all areas of Number Theory, with emphasis on Computational Number Theory and applications to Cryptography. Researchers in these fields of study are welcomed to participate, as we honour Canada's foremost computational number theorist, whose contributions include results on integer factorization, primality testing, diophantine equations, linear recurrences, the infrastructure of quadratic number fields and function fields, and their applications to Cryptography. Each day of the conference will include one plenary lecture, a number of invited lectures and time has been set aside each day for contributed talks.
    Special Lecture
    Manindra Agrawal from IITK, who has recently proved the existence of a deterministic polynomial time algorithm for primality testing, will give a special evening lecture at the Banff Center on Sunday May 25, 2003, with a reception to follow in his honour sponsored by RSA Security Inc.

I have particular interests in results associated with lattice points close to (or on) a curve or surface, the distribution of special sequences of integers in short intervals, applications of Pade approximations to Number Theory, the irreducibility of polynomials over the rationals, and computations with sparse or lacunary polynomials. Richard Hudson Research Interests: elementary number theory, analytic prime number theory, quadratic forms, class number formulae, forms of higher order, quadratic and higher power residues, comparative prime number theory, Gauss and Jacobi sums, computer results in number theory. Kate Hurley Research Interests: My research concerns modularity properties of VOAs. One can associate a q-graded function called a graded trace or one-point correlation function to a given VOA, and in some cases these functions are modular forms. I have worked on determining which modular forms are realized as graded traces. An additional recent interest of mine is inverse Galois theory. Charles Nicol (Retired but still collaborating in research) Research Interests: aspects of Computational and Elementary Number Theory, including work on cyclotomic polynomials, Euler's phi function, and problems related to digits in integer sequences.
