= Frobenius–Schur indicator
{wiki=Frobenius–Schur_indicator}
The Frobenius–Schur indicator is a concept from representation theory, particularly concerning finite groups and their representations. It provides a way to classify irreducible representations of a finite group with respect to their behavior under certain types of symmetry. In more specific terms, the Frobenius–Schur indicator is defined for an irreducible representation of a finite group \\( G \\) over a field \\( K \\) (typically, the complex numbers).
