In the recent years, the trace norm of graphs has been extensively studied under the name of graph energy. The trace norm is just one of the Ky Fan k-norms, given by the sum of the k largest singular values, which are studied more generally in the present paper. Several relations to chromatic number

It is shown that, for any n x n stochastic matrix A=(aij), #(6ij) which can be imbedded in a continuous time Markov chain, there exist distinct indices i,j such that for all k aik = 0 implies a~k = 0, and likewise distinct indices i',j' such that, for all k, aki,=-O implies akj,=O. The present proo
