Moore-penrose involutions in the classes of laplacians and simplices

The Moore-Penrose generalized inverse defines an involution in the class of real positive definite n×n matrices with rank n−1 and row-sums zero. We show that there is an analogous situation for weighted undirected graphs on n vertices and for classes (n−1)-simplices in a Euclidean (n−1)-space.
