22. Arithmetic Algebraic Geometry A European network of 12 working groups from 6 countries. http://www.arithgeom-network.univ-rennes1.fr/

A Research Training Network of the European Union Overview Partners Programme Positions Activities Project overview Developing powerful methods taken from geometry to study the arithmetical properties of algebraic equations Algebraic equations and their arithmetical properties have interested mankind since antiquity. One has only to think of the works of Pythagoras and Diophantus, which were a milestone in their time. For many centuries such problems have fascinated both serious mathematicians (Fermat, Gauss, ...) and amateurs alike. However, developments in recent years have transformed the subject into one of the central areas of mathematical research, which has relations with, or applications to, virtually every mathematical field, as well as an impact to contemporary everyday life (for example, the use of prime numbers and factorisation for encoding "smart" cards). The classical treatment of equations by analysis and geometry in the realm of complex numbers in this century has found a counterpart, in the similar theories over finite and p -adic fields, which have particular significance for arithmetic questions. The study of certain functions encoding arithmetic information and generalising the Riemann zeta-function (

The Egyptian Zero Egyptian Counting Addition Subtraction ... Egyptian Fractions EYPTIAN COUNTING WITH HEIROGLYPHS These are the basic glyphs (symbols) used in Egypt for counting over 4000 years ago: Writing an integer consists of writing the number (from to 9) of the proper symbols to represent the integer. Thus, There is also a glyph which can translated as "equals" and a compact way of writing large glyphs, as shown below on the right, for two ways 35: in early Egypt Addition and subtraction were simple processes using the counting glyphs . To add two numbers, collect all symbols of similar type and replace a ten of one type by one of the next higher order. For example, adding 35 and 17: add Subtraction is a reversal of the process, if necessary replace a higher, so subtract Multiplication and Division Multiplication and Division were also simple processes using the counting glyphs . To multiply two numbers, all you needed to understand was the double or the half of an integer; i.e., the 2 times table.

PUBLICATIONS Summer School 2006 Clay Mathematics Institute 2006 Summer School Arithmetic Geometry July 17 - August 11 New-Videos of Lectures Schedule Travel information Overview Designed for graduate students and mathematicians within five years of their Ph.D., the program will introduce the participants to modern techniques and outstanding conjectures at the interface of number theory and algebraic geometry. The main focus is rational points on algebraic varieties over non-algebraically closed fields. Do they exist? If not, can this be proven efficiently and algorithmically? When rational points do exist, are they finite in number and can they be found effectively? When there are infinitely many rational points, how are they distributed? For curves, a cohesive theory addressing these questions has emerged in the last few decades. Highlights include Faltings' finiteness theorem and Wiles' proof of Fermat's Last Theorem. Key techniques are drawn from the theory of elliptic curves, including modular curves and parametrizations, Heegner points, and heights. The arithmetic of higher-dimensional varieties is equally rich, offering a complex interplay of techniques including Shimura varieties, the minimal model program, moduli spaces of curves and maps, deformation theory, Galois cohomology, harmonic analysis, and automorphic functions. However, many foundational questions about the structure of rational points remain open, and research tends to focus on properties of specific classes of varieties.

Galois Field Arithmetic Library www.partow.net .: Home :. .: Links :. .: Search :. .: Contact :. Main Menu About Projects Programming Miscellaneous Projects Digital Image Watermarking FastGEO Particle Engine Simulation - (P.E.S) N-Mice Simulation ... Description The branch in mathematics known as Galois theory (pronounced as "gal-wah") which is based on abstract algebra was discovered by a young brilliant french mathematician known as Evariste Galois. The branch deals mainly with the analysis and formal description of binary and unary operations upon polynomials comprised of elements within a Galois field that then describe polynomials within the field itself. The C++ Galois Field Arithmetic Library, implements a specialised version of Galois Fields known as extension fields or in other words fields of the form GF(2^m) and was developed as a base for programming tasks that involved cryptography and error correcting codes. The library is simple, consise and straight forward, it also uses a series of look-up tables to increase performance of calculations. The library is broken into three classes, Galois Field, Galois Field Element and Galois Field Polynomial. Operations such as addition, subtraction, multiplication, division, modulus and exponentiation can occur over both field elements and field polynomials and also left and right shifting can occur for field polynomials.

Home Beginners Experienced Investors Active Traders ... Trading Arithmetic Mean A mathematical representation of the typical value of a series of numbers, computed as the sum of all the numbers in the series divided by the count of all numbers in the series. Arithmetic mean is commonly referred to as "average" or simply as "mean". Suppose you wanted to know what the arithmetic mean of a stock's closing price was over the past week. If during the five-day week the stock closed at $14.50, $14.80, $15.20, $15.50, and then $14.00, its arithmetic mean closing price would be equal to the sum of the five numbers ($74.00) divided by five, or $14.80.

Cite this entry Search the SEP Advanced Search Tools ... Please Read How You Can Help Keep the Encyclopedia Free Frege's Logic, Theorem, and Foundations for Arithmetic First published Wed Jun 10, 1998; substantive revision Fri Apr 13, 2007 Frege formulated two distinguished formal systems and used these systems in his attempt both to express certain basic concepts of mathematics precisely and to derive certain mathematical laws from the laws of logic. In his Begriffsschrift of 1879, he developed a second-order predicate calculus and used it both to define interesting mathematical concepts and to state and prove mathematically interesting propositions. However, in his Grundgesetze der Arithmetik of 1893/1903, Frege added (as an axiom) what he thought was a distinguished logical proposition (Basic Law V) and tried to derive the fundamental theorems of various mathematical (number) systems from this proposition. Unfortunately, not only did Basic Law V fail to be a logical proposition, but the resulting system proved to be inconsistent, for it was subject to Russell's Paradox. Although the inconsistency in Frege's Grundgesetze is widely known, it is not very well known that a deep theoretical accomplishment can be extracted from his work. The

40. Greek Numbers And Arithmetic Greek Numbers and arithmetic. The earliest numerical notation used by the Greeks The arithmetic operations are complex in that so many symbols are used. http://www.math.tamu.edu/~dallen/history/gr_count/gr_count.html

Next: About this document Greek Numbers and Arithmetic The earliest numerical notation used by the Greeks was the Attic system. It employed the vertical stroke for a one, and symbols for ``5", ``10", ``100", ``1000", and ``10,000". Though there was some steamlining of its use, these symbols were used in a similar way to the Egyptian system, being that symbols were used repeatedly as needed and the system was non positional. By the Alexandrian Age, the Greek Attic system of enumeration was being replaced by the Ionian or alphabetic numerals. This is the system we discuss. The (Ionian) Greek system of enumeration was a little more sophisticated than the Egyptian though it was non-positional. Like the Attic and Egyptian systems it was also decimal. Its distinguishing feature is that it was alphabetical and required the use of more than 27 different symbols for numbers plus a couple of other symbols for meaning. This made the system somewhat cumbersome to use. However, calculation lends itself to a great deal of skill within almost any system, the Greek system being no exception. Greek Enumeration and Basic Number Formation First, we note that the number symbols were the same as the letters of the Greek alphabet.
