Dirichlet Fractional Laplacian in multi-tubes

Spectral Theory 2023-08-01 v3

Abstract

We describe the spectrum structure for the restricted Dirichlet fractional Laplacian in multi-tubes, i.e. domains with cylindrical outlets to infinity. Some new effects in comparison with the local case are discovered. In this version, Theorem 4 is essentially improved.
