Antihomomorphism

An antihomomorphism is a concept from the field of abstract algebra, specifically in the study of algebraic structures such as groups, rings, and algebras. It is a type of mapping between two algebraic structures that reverses the order of operations. Formally, let \( A \) and \( B \) be two algebraic structures (like groups, rings, etc.) with a binary operation (denoted \( * \)).
