Abstract

Let K be a conjugacy class of a finite p-group G where p is a prime, and let K-1 denote the conjugacy class of G consisting of the inverses of the elements in K. We observe that, in several cases, the number of elements in the product KK-1 is congruent to 1 modulo p -1, and we pose the question in which generality this congruence is valid. We also consider related properties of the class multiplication constants of G. Furthermore, let χ be an irreducible character of G, and let χ- denote the complex conjugate of χ. We show that, in several cases, the number of irreducible constituents of the product χχ- is congruent to 1 modulo p -1, and we pose the question in which generality this congruence is valid.

N2 - Let K be a conjugacy class of a finite p-group G where p is a prime, and let K-1 denote the conjugacy class of G consisting of the inverses of the elements in K. We observe that, in several cases, the number of elements in the product KK-1 is congruent to 1 modulo p -1, and we pose the question in which generality this congruence is valid. We also consider related properties of the class multiplication constants of G. Furthermore, let χ be an irreducible character of G, and let χ- denote the complex conjugate of χ. We show that, in several cases, the number of irreducible constituents of the product χχ- is congruent to 1 modulo p -1, and we pose the question in which generality this congruence is valid.
