Spectrum of the schrodinger operator in a perturbed periodically twisted tube

Original language description

We study Dirichlet Laplacian in a screw-shaped region, i.e. a straight twisted tube of a non-circular cross section. It is shown that a local perturbation which consists of "slowing down" the twisting in the mean gives rise to a non-empty discrete spectrum.

Czech description

Studujeme Dirichletův Laplacián ve šroubovité oblasti; ukazujeme, že lokální ?zpomalení? torze vede ke vzniku diskrétního spektra.
