DirichletCharacter

DirichletCharacter[k, j, n]
gives the Dirichlet character with modulus k and index j.

DetailsDetails

  • Integer mathematical function, suitable for both symbolic and numerical manipulation.
  • DirichletCharacter[k, j, n] picks a particular ordering for possible Dirichlet characters modulo k.
  • There are distinct Dirichlet characters for a given modulus k, as labeled by the index j. Different conventions can give different orderings for the possible characters.
  • DirichletCharacter[k, j, n] is periodic in n with period k.
  • DirichletCharacter[k, j, n] is zero when n is not coprime to k.
  • DirichletCharacter[k, j, n] is a multiplicative function in n.
