Lisbon Webinar in Analysis in Differential Equations

Absence of positive eigenvalues of magnetic Schroedinger operators

Transmissão através de Videoconferência

Speaker: Hynek Kovařík (Università degli studi di Brescia).

Absence of positive eigenvalues of magnetic Schroedinger operators We study sufficient conditions for the absence of positive eigenvalues of magnetic Schroedinger operators in R^n. In our main result we prove the absence of eigenvalues above certain threshold energy which depends explicitly on the magnetic and electric field. A comparison with the examples of Miller-Simon shows that our result is sharp as far as the decay of the magnetic field is concerned.

The talk is based on a joint work with Silvana Avramska-Lukarska and Dirk Hundertmark.

The Lisbon Webinar in Analysis in Differential Equations is a joint iniciative of CAMGSD, CMAFcIO and GFM, three research centers of the University of Lisbon. It is aimed at filling the absence of face-to-face seminars and wishes to be a meeting point of mathematicians working in the field.

14h30-15h30

A conferência visa reunir os principais especialistas no domínio da Imagiologia Médica por Micro-ondas (MMWI) e incluirá palestras, apresentações e pósteres de resumos revistos por pares e artigos de conferências, bem como workshops em áreas satélite de investigação com interesse para a investigação em MMWI.
