Analysis and/of PDE: Improved eigenvalue bounds for Schrödinger operators with slowly decaying potentials
14 November 2019 14:00 in CM301
We extend a result of Davies and Nath  on the location of eigenvalues of Schrödinger operators $-\Delta+V$ with slowly decaying complex-valued potentials to higher dimensions. We also discuss examples related to the Laptev--Safronov conjecture , which stipulates that the absolute value of any complex eigenvalue can be bounded in terms of the $L^q$ norm of $V$, for a certain range of exponents $q$. The talk is based on .
