gives the Dirichlet L-function for the Dirichlet character with modulus k and index j.


  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • For , , where is a Dirichlet character.
  • The possible Dirichlet characters modulo k are specified by an index j, and given by DirichletCharacter[k,j,n].
  • DirichletL[k,j,s] can be evaluated to arbitrary numerical precision for integer k and j, and arbitrary complex s.
  • DirichletL automatically threads over lists.
