Simulation of detection and scattering of sound waves by the lateral line of a fish
V. M. Adamyan, I. Y. Popov, I. V. Blinova +1
An explicitly solvable model of sound sources detection and sound wave scattering by the lateral line of a fish or amphibian based on the theory of self-adjoint perturbations of th…
Boundary triplets, tensor products and point contacts to reservoirs
A. A. Boitsev, J. F. Brasche, M. M. Malamud +2
We consider symmetric operators of the form where is symmetric and is (in general) unbounded. Such operato…
Point contacts and boundary triples
Vladimir Lotoreichik, Hagen Neidhardt, Igor Yu. Popov
We suggest an abstract approach for point contact problems in the framework of boundary triples. Using this approach we obtain the perturbation series for a simple eigenvalue in th…
A remark on Schatten-von Neumann properties of resolvent differences of generalized Robin Laplacians on bounded domains
Jussi Behrndt, Matthias Langer, Igor Lobanov +2
In this note we investigate the asymptotic behaviour of the -numbers of the resolvent difference of two generalized self-adjoint, maximal dissipative or maximal accumulative Rob…
Lower bound on the spectrum of the Schrödinger operator in the plane with delta-potential supported by a curve
Igor Lobanov, Vladimir Lotoreichik, Igor Popov
We consider the Schrödinger operator in the plane with delta-potential supported by a curve. For the cases of an infinite curve and a finite loop we give estimates on the lower bou…
