Definition of a field mathematics
In mathematics, a field is a set on which addition, subtraction, multiplication, and division are defined and behave as the corresponding operations on rational and real numbers do. A field is thus a fundamental algebraic structure which is widely used in algebra, number theory, and many other areas of … See more Informally, a field is a set, along with two operations defined on that set: an addition operation written as a + b, and a multiplication operation written as a ⋅ b, both of which behave similarly as they behave for See more Finite fields (also called Galois fields) are fields with finitely many elements, whose number is also referred to as the order of the field. The above … See more Historically, three algebraic disciplines led to the concept of a field: the question of solving polynomial equations, algebraic number theory, and algebraic geometry. A first step towards the notion of a field was made in 1770 by Joseph-Louis Lagrange, who observed that … See more Since fields are ubiquitous in mathematics and beyond, several refinements of the concept have been adapted to the needs of particular mathematical areas. Ordered fields See more Rational numbers Rational numbers have been widely used a long time before the elaboration of the concept of field. They are numbers that can be written as See more In this section, F denotes an arbitrary field and a and b are arbitrary elements of F. Consequences of the definition One has a ⋅ 0 = 0 and −a = (−1) ⋅ a. In particular, one may deduce the additive inverse of every element as soon as one knows −1.
