A **multiplicative character** is a type of mathematical function used in number theory, particularly in the context of Dirichlet characters and L-functions. Specifically, a multiplicative character is a homomorphism from the group of non-zero integers under multiplication to a finite abelian group, such as the group of complex numbers of modulus one.
