The equality of generalized matrix functions on the set of all symmetric matrices

Abstract: A generalized matrix function d G χ : M n (C) → C is a function constructed by a subgroup G of S n and a complex valued function χ of G. The main purpose of this paper is to find a necessary and sufficient condition for the equality of two generalized matrix functions on the set of all symmetric matrices, S n (C). In order to fulfill the purpose, a symmetric matrix S σ is constructed and d G χ (S σ ) is evaluated for each σ ∈ S n . By applying the value of d G χ (S σ ), it is shown that d G χ (AB) = d G χ (A)d… Show more
