Abstract
We study crossed S-matrices for braided G-crossed categories and reduce their computation to a submatrix of the de-equivariantization. We study the more general case of a category containing the symmetric category Rep(A,z) with A a finite cyclic group and z∈A such that z2=1. We give two examples of such categories, which enable us to recover the Fourier matrix associated with the big family of unipotent characters of the dihedral groups with automorphism as well as the Fourier matrix of the big family of unipotent characters of the Ree group of type F42.
