{wiki=Finite_character}
In the context of mathematics, particularly in the field of representation theory, a **finite character** refers to a homomorphism from a group (often a finite group or a compact group) into the multiplicative group of non-zero complex numbers (or into a field). Characters are used to study the representations of groups, particularly in the context of finite groups and their representations over the complex numbers.
