Multiplicative Character


A continuous homomorphism of a group into the nonzero complex numbers. A multiplicative character omega gives a group representation on the one-dimensional space C of complex numbers, where the group representation action by g in G is multiplication by omega(g). A multiplicative character is unitary if it has absolute value 1 everywhere.
