Extension theory and localization of resonances for domains of trap type
I. Yu. Popov Leningrad Institute of Precision Mechanics and Optics
Abstract:
The existence of a series of resonances located near the real axis is proved for the problem of scattering on a domain with a small aperture (narrow slit) (a domain of trap type). A method is presented for computing the resonances, based on a model of slits of zero width, based in turn on the theory of selfadjoint extensions of symmetric operators.
