Spectral analysis of non-local Schrödinger operators
arXiv:1603.01626
Abstract
We study spectral properties of convolution operators and their perturbations by compactly supported potentials. Results are applied to determine the front propagation of a population density governed by operator with a compactly supported initial density provided that has positive eigenvalues. If there is no positive spectrum, then the stabilization of the population density is proved.
