Abstract

Let GG be a finite group. An element gg of GG is called a vanishing element if there exists an irreducible character χ\chi of GG such that χ(g)=0\chi(g) = 0; in this case, we say that the conjugacy class of gg is a vanishing conjugacy class. In this paper, we discuss some arithmetical properties concerning the sizes of the vanishing conjugacy classes in a finite group.
