Let S denote either the set of n Γ— n symmetric doubly stochastic matrices or the set of n Γ— n symmetric doubly substochastic matrices and let T be a linear map on span S. We prove that T (S) = S if and only if there exists an n Γ— n permutation matrix P such that T (X) = P t XP for all X ∈ span S. Ou
