Some variational principles over finite dimentional Hilbert spaces

Abstract

In this paper a new variational approach concerning functions (continuous) over Hilbert spaces is presented.

The general construction had a certain flaw especially in the first pages (first lemma). The completion of the orthogonal basis in the way indicated doesn't always exist therefore i own my apologies to "Ky-Fan" readers (reviewers) and thus this paper (in all versions) is withdrawn
