Abstract: We prove that for any fixed trigonometric polynomial potential satisfying a genericity condition, the spectrum of the two-dimensional periodic Schrödinger operator has finite multiplicity ...

Abstract: In this paper we propose a fast method to compute the longitudinal extension of surfaces using the extrema of the first eigenfunction of Laplace-Beltrami Operator and the hot spots ...

ABSTRACT: We prove equiconvergence of the Bochner-Riesz means of the Fourier series and integral of distributions with compact support from the Liouville spaces.
