Kvantový kroužek ONLINE: Denis Borisov - Accumulation of resonances and eigenvalues for operators wi
22 Dec 2020 14:45
Srdečně vás zveme na poslední letošní seminář v rámci Kvantového kroužku ONLINE. Prostřednictvím platformy Zoom bude hovořit Denis Borisov (Bashkir State Pedagogical University, Ufa) na téma Accumulation of resonances and eigenvalues for operators with distant perturbations. Seminář se koná v úterý 22. 12. 2020 od 14.45 hod. Zoom-ové souřadnice, které vám umožní se semináře zúčastnit, najdete na webu Kvantového kroužku.
Abstract:
We consider a model one-dimensional problem with distant perturbations,for which we study a phenomenon of emerging of infinitely many eigenvalues and resonances near the bottom of the essential spectrum. We show that they accumulate to a certain segment of the essential spectrum. Then we discuss possible generalization of this result to multi-dimensional models and various situations of resonances and eigenvalues distributions.
