AB  - In this paper we give a geometric mean and mean of
p-th degree of singular values for almost all graphs. We prove three
theorems about a conjecture of V. Nikiforov for Schatten p-norm
of graphs when p > 2. We prove that the conjecture is true when
p is an even integer or when graph is a tree or a strongly regular
graph with certain parameters. The strongly regular graphs with
these parameters are graphs with maximal energy
