About

A field is a set equipped with two operations, addition and multiplication, that satisfy certain properties. These properties include closure, associativity, commutativity, distributivity, the existence of additive and multiplicative identities, and the existence of additive and multiplicative inverses (except for the additive identity). Fields are an important structure in algebra and provide a foundation for many branches of mathematics, including number theory, algebraic geometry, and abstract algebra. The page also discusses subfields, extensions, finite fields, characteristic of a field, and applications of fields in computer science and physics. Additionally, the page explores various examples of fields, such as the rational numbers, real numbers, complex numbers, and finite fields. Overall, the page provides a comprehensive introduction to the concept of a field in mathematics and its applications.

Algebraic structure

In mathematics, an algebraic structure consists of a nonempty set A (called the underlying set, carrier set or domain), a collection of operations on A (typically binary operations such as addition and multiplication), and a finite set of identities, known as axioms, that these operations must satisfy.
