Human: The article delves into the fundamental algebraic structures utilized in abstract algebra - a ring. Consisting of a set equipped with two binary operations that generalize arithmetic addition and multiplication, this concept generalizes theorems from arithmetic to non-numerical objects like polynomials, series, matrices, and functions. A ring is defined as an abelian group augmented with a second binary operation that exhibits associative properties, distributes over the abelian group operation, and features an identity element. This structure expands upon the integers' fundamental group operation and secondary operation. Commutative or non-commutative - the question of whether elements in a ring can be multiplied in any order without altering the outcome profoundly affects its behavior as an abstract object. As such, commutative ring theory - known colloquially as commutative algebra - has become a crucial topic within the realm of ring theory. Notably, the development of this subject area has been heavily influenced by naturally occurring problems and ideas from both algebraic number theory and algebraic geometry. Examples of commutative rings abound - including the integers, polynomials, the coordinate ring of an affine variety, and the integers of a number field. Conversely, non-commutative rings feature n ? n real matrices with n ? 2, group rings in representation theory, operator algebras in functional analysis, and the cohomology ring of a topological space. The conception of this concept began to take shape in the late nineteenth century, evolving into a full-fledged concept by the early twentieth century. Mathematicians such as Dedekind, Hilbert, Fraenkel, and Noether contributed significantly to its development, initially motivated by the study of Dedekind domains, polynomial rings, and invariants. Ultimately, this fundamental algebraic structure has also found practical application in areas like geometry and mathematical analysis - demonstrating its wide-ranging versatility.
