摘要：
A complex character chi of a finite group G is called sharp if vertical bar G vertical bar = Pi(a)(is an element of L chi) (chi (1) - a) where L chi := {chi (g) vertical bar 1 not equal g is an element of G}. In this paper we give a characterization of finite groups all non-linear irreducible characters of which are sharp.
