Disreteness of the spectrum for the Laplace - Beltrami operator and metric transformation on manifold

Бесплатный доступ

In this paper we proof the conservation property for the discreteness of the spectrum for the Laplace - Beltrami operator on the simple warped products of order k with the special kind of quasi-isometric transformation of the metric. Also, we make some notes for the Schro¨dinger operator case.
