is a multiple of
where L
is the image of c on
(cf. [2] and [3]). That c is said to be sharp of type L if
Some of permutation characters are
well-known examples of sharp characters. Given a finite group G,
how can we determine the sharp characters of G?
In this paper, we show several methods to do it.
