Number theory From Wikipedia, the free encyclopedia. Traditionally, number theory is that branch of pure mathematics concerned with the properties of integers and contains many open problems that are easily understood even by non-mathematicians. More generally, the field has come to be concerned with a wider class of problems that arose naturally from the study of integers. Number theory may be subdivided into several fields according to the methods used and the questions investigated. See for example the list of number theory topics The term " arithmetic " is also used to refer to number theory. This is a somewhat older term, which is no longer as popular as it once was. Nevertheless, the term remains prevalent e.g. in the names of mathematical fields (arithmetic algebraic geometry and the arithmetic of elliptic curves and surfaces). This sense of the term arithmetic should not be confused with the branch of logic which studies arithmetic in the sense of formal systems. In elementary number theory , the integers are studied without use of techniques from other mathematical fields. Questions of

MathTools Math routines for the TI-89/92+/V200 Linear Algebra, Polynomials, Calculus, Statistics, Special Functions, Vector Analysis, and more Version: 2.4.3 Author: Bhuvanesh Bhatt ( bbhatt1@towson.edu Introduction A Computer Algebra System (CAS) is a kind of mathematical software that enables you to use a computer to manipulate mathematical expressions. A CAS has symbolics, numerics, graphics, programming, and typesetting capabilities, and usually also data import/export. CAS’s are used in many fields such as mathematics, physics, chemistry, engineering, computer science, computational biology, economics, and education. The TI-68k devices (TI-89, TI-92 Plus, and Voyage 200) are the most advanced calculators available today. Once you have learned a topic, you can use the TI-68k CAS to automate some or all of your work, so that you can concentrate on more advanced and/or abstract topics without worrying about calculational errors. The TI-68k are also invaluable when learning a topic, since they allow you to explore the topic in many ways. One problem with the TI-68k is that a lot of commonly used functions are not built-in. MathTools aims to bridge that gap, mainly in the area of mathematics. One of my goals in maintaining MathTools and its extensive documentation is to introduce people to the beauty of mathematics. MathTools mainly consists of TI-Basic functions, but there are also TI-Basic programs, math programs and utilities written in C, and a Flash application.

The purpose of the CNTA is to enhance and promote learning and research in Number Theory, particularly in Canada. To advance these goals the CNTA organizes major international conferences, with the aim of exposing Canadian students and researchers to the latest developments in number theory. The previous meetings have been held in Banff (1988), Vancouver (1989), Kingston (1991), Halifax (1994), Ottawa (1996), Winnipeg (1999) and Montreal (2002). These have been high quality conferences which have had wide participation of the international number theory community.

Primes and prime factorization are especially important in number theory, as are a number of functions such as the divisor function Riemann zeta function , and totient function . Excellent introductions to number theory may be found in Ore (1988) and Beiler (1966). The classic history on the subject (now slightly dated) is that of Dickson (1952). The great difficulty required to prove relatively simple results in number theory prompted no less an authority than Gauss to remark that "it is just this which gives the higher arithmetic that magical charm which has made it the favorite science of the greatest mathematicians, not to mention its inexhaustible wealth, wherein it so greatly surpasses other parts of mathematics." Gauss, often known as the "prince of mathematics," called mathematics the "queen of the sciences,"' and considered number theory the "queen of mathematics" (Beiler 1966, Goldman 1997).

Notes on Elementary Number Theory These are links to PostScript files containing notes for various topics in elementary number theory. My favorite text (and one I've used since the first edition) is Kenneth Rosen's Elementary Number Theory and Its Applications . The lecture notes follow the book fairly closely in the order of the topics. A couple of differences worth noting: I'm using a backward recurrence due to S. P. Glasby for the Extended Euclidean Algorithm, and the proof of quadratic reciprocity is due to J. S. Frame. Glasby's backward recurrence is particularly good for hand (but not necessarily machine ) computation. The current edition of Rosen's book (the 4-th edition) has a few misprints, but is pretty good. The exercises continue to be excellent, and I like the brief biographies of mathematicians mentioned in the exposition. The elementary treatment of topics (no abstract algebra required) means that the course does not have heavy prerequisites; I can expect 1020 students when we offer it every other year. How do I view/print the notes?

71. Math Applets: IntegerZone And TenBlocks TenBlocks turns the times tables into a series of puzzles. IntegerZone lets users explore aspects of arithmetic and number theory using the integers themselves as the interface. http://www.1729.com/applets/

The Java programming language creates opportunities that have not previously existed - it is a high-level language, with a freely distributed development kit and run-time engine. By writing code in the form of Java applets, distributing code to users is as easy as getting them to view a web page, and they can execute your code at little or no risk to their own system, because of Java's built in security features. The IntegerZone presents the set of integers as a resizeable and scrollable rectangular grid, and presents a menu of different interaction modes, each one demonstrating or testing different aspects of arithmetic and number theory. TenBlocks presents the multiplication table as a series of simple puzzles: for each multiplication problem, present it as a grid of squares of the corresponding height and width, and require the user to fill it in with blocks of ten squares of two basic shapes, until there are less than ten squares left unfilled. The hardest one seems to be 9 times 9, because you can only have one square left over when you are finished. To download both applets for use on a home or school computer, see the

UIC Honors Seminar in Cryptography Spring, 2002 Elementary Number Theory A Lightning Course Number theory is the mathematical study of the integers and their generalizations. The portion of number theory needed to understand the basic public key algorithms is elementary and dates back to the work of Pierre de Fermat and Leonhard Euler. Integers and rational numbers. An integer is a positive or negative whole number, or zero. A rational number is a positive or negative fraction, or zero. Prime numbers and composite numbers. A prime number is an integer n with no divisors other than 1 and n. A composite number is an integer which is not prime. The first few prime numbers are 2,3,5,7,11,13,.... There are infinitely many prime numbers. (This result is due to Euclid. Lists of prime numbers can be constructed by a process called the Sieve of Eratosthenes, described in a University of Utah Math 216 Problem Set. Factoring. Any positive integer can be written in only one way (up to order) as a product of powers of prime numbers. 12=(3)(2)(2) and 124=(2)(2)(31) This result was proved carefully by Gauss in his Disquisitiones Arithmeticae. Writing an integer as a product of primes is called

(This is also explained in the first day handout below.) Each chapter starts with the pre-lab sheet. It contains background, exercises to be worked by hand, and may mention the larger questions which will be taken up in the computer lab. Each student turns in their individual answers to pre-lab questions the following class, which is . . . The next 2-3 classes are held in the lab. Students work through the lab notebooks in teams of two. Each notebook contains "Research questions" and "Exercises". Exercises are intended to be straightforward while research questions are not. Typically, the research questions will require experimentation, forming of conjectures, and proofs. We expect students to make varying degrees of progress on these questions.
