GROUP THEORY SYMBOL

GTIrep

GTIrep[characters,character table]
gives the number of times an irreducible representation appears in a reducible representation with given characters.

DetailsDetails

  • For a finite group the number of times that an irreducible representation appears in a reducible representation is given by .
  • All elements in the same class have the same character.
  • The vector characters contains the characters of each class of the reducible representation.
