A 'ring' in mathematics is an algebraic structure consisting of a set equipped with two binary operations: addition and multiplication, where addition forms an abelian group, multiplication is associative, and multiplication distributes over addition. Rings generalize fields by not requiring multiplicative inverses for every non-zero element, making them fundamental in abstract algebra and number theory.

An algebraic structure is a set equipped with one or more operations that follow specific axioms, providing a framework to study algebraic systems like groups, rings, and fields. These structures allow mathematicians to abstract and generalize patterns and properties across different mathematical systems, facilitating deeper understanding and applications across various domains.

Binary operations are mathematical operations that combine two elements from a set to produce another element of the same set. They are foundational in algebraic structures like groups, rings, and fields, where they help define the structure's properties and operations.

An Abelian group is a set equipped with a binary operation that is associative, has an identity element, includes an inverse for each element, and is commutative. This structure is fundamental in abstract algebra and underpins many areas of mathematics, including number theory and topology.

A non-zero element refers to any element in a set, vector, or matrix that is not equal to zero, playing a crucial role in various mathematical operations and properties, such as determining the rank of a matrix or the support of a vector. Understanding non-zero elements is essential for solving linear equations, performing matrix factorizations, and analyzing sparsity in data structures.

Abstract algebra is a branch of mathematics that studies algebraic structures such as groups, rings, and fields, focusing on their properties and the relationships between them. It provides a unifying framework for understanding mathematical concepts and solving problems across various areas of mathematics and science.

abstract algebra

Number theory is a branch of pure mathematics devoted to the study of the integers and integer-valued functions, exploring properties such as divisibility, prime numbers, and the solutions to equations in integers. It has deep connections with other areas of mathematics and finds applications in cryptography, computer science, and mathematical puzzles.
