GTDirectProductChars

GTDirectProductChars[characters1,characters2]
gives the character system of a direct product representation from the character systems of two given representations.

DetailsDetails

  • All elements in the same class have the same character.
  • The character system is given as a vector containing the character of each class.
  • For two unitary representations and , the character system of the direct product representation is given by .
