Prerequisite — Mathematics Algebraic Structure. Then R is said to form a ring w. Therefore a non- empty set R is a ring w. Before discussing further on rings, we define Divisor of Zero in A ring and the concept of unit. Divisor of Zero in A ring — In a ring R a non-zero element is said to be divisor of zero if there exists a non-zero element b in R such that a. Obviously if R is a commutative ring then if a is a left divisor of zero then a is a right divisor of zero also. Units — In a non trivial ring R Ring that contains at least to elements with unity an element a in R is said to be an unit if there exists an element b in R such that a.

This book constitutes an elementary introduction to rings and fields, in particular Galois rings and Galois fields, with regard to their application to the theory of quantum information, a field at the crossroads of quantum physics, discrete mathematics and informatics. The existing literature on rings and fields is primarily mathematical. There are a great number of excellent books on the theory of rings and fields written by and for mathematicians, but these can be difficult for physicists and chemists to access. This book offers an introduction to rings and fields with numerous examples. It contains an application to the construction of mutually unbiased bases of pivotal importance in quantum information. It is intended for graduate and undergraduate students and researchers in physics, mathematical physics and quantum chemistry especially in the domains of advanced quantum mechanics, quantum optics, quantum information theory, classical and quantum computing, and computer engineering.

A ring in the mathematical sense is a set together with two binary operators and commonly interpreted as addition and multiplication, respectively satisfying the following conditions:. Additive associativity: For all , ,. Additive commutativity: For all , ,. Additive identity : There exists an element such that for all , ,. Additive inverse : For every there exists such that ,. Left and right distributivity: For all , and ,. Multiplicative associativity: For all , a ring satisfying this property is sometimes explicitly termed an associative ring.

Ring (mathematics)

Algebraic number theory. Noncommutative algebraic geometry. In mathematics , rings are algebraic structures that generalize fields : multiplication need not be commutative and multiplicative inverses need not exist. In other words, a ring is a set equipped with two binary operations satisfying properties analogous to those of addition and multiplication of integers. Ring elements may be numbers such as integers or complex numbers , but they may also be non-numerical objects such as polynomials , square matrices , functions , and power series.

Linear algebra is one of the most applicable areas of mathematics. It is used by the pure mathematician and by the mathematically trained scien-tists of all disciplines. This book is directed more at the former audience. Discrete Mathematics - Algebraic Structures 1.

CS21001 Discrete Structures, Autumn 2005

Она с самого начала возражала против его кандидатуры, но АНБ посчитало, что другого выхода. Хейл появился в порядке возмещения ущерба. После фиаско Попрыгунчика. Четыре года назад конгресс, стремясь создать новый стандарт шифрования, поручил лучшим математикам страны, иными словами - сотрудникам АНБ, написать новый супералгоритм. Конгресс собирался принять закон, объявляющий этот новый алгоритм национальным стандартом, что должно было решить проблему несовместимости, с которой сталкивались корпорации, использующие разные алгоритмы. Конечно, просить АН Б приложить руку к совершенствованию системы общего пользования - это все равно что предложить приговоренному к смертной казни самому сколотить себе гроб. ТРАНСТЕКСТ тогда еще не был создан, и принятие стандарта лишь облегчило бы процесс шифрования и значительно затруднило АНБ выполнение его и без того нелегкой задачи.

Она посмотрела на беретту и внезапно почувствовала тошноту. - Вы действительно собираетесь пристрелить Грега Хейла. - Нет.  - Стратмор хмуро посмотрел на нее и двинулся к двери.  - Но будем надеяться, что он этого не узнает. ГЛАВА 76 У подъезда севильского аэропорта стояло такси с работающим на холостом ходу двигателем и включенным счетчиком. Пассажир в очках в тонкой металлической оправе, вглядевшись сквозь стеклянную стену аэровокзала, понял, что прибыл вовремя.

    (R;+,·) and (Q;+,·) serve as examples of fields,. (Z;+,·) is an example of a ring which is not a field. We may ask which other familiar structures come equipped with.
