= Dirichlet L-function
{wiki=Dirichlet_L-function}
The Dirichlet L-function is a complex function that generalizes the Riemann zeta function and plays a crucial role in number theory, particularly in the study of Dirichlet characters and L-series. It is associated with a Dirichlet character \\( \\chi \\) modulo \\( k \\), which is a completely multiplicative arithmetic function satisfying certain periodicity and the condition \\( \\chi(n) = 0 \\) for \\( n \\) not coprime to \\( k \\).
