Let G be a finite group with given subgroups H and K. π an irreducible complex representation of such that its space H-invariant vectors as well the K-invariant are both one dimensional. vH (resp. vK) denote K-invariant) vector unit norm in G-invariant inner product 〈,〉π on π. Our interest is computing square absolute value 〈vH,vK〉π. This correlation constant c(π;H,K) defined by Gross [3]. In t...
