The Spectrum of Speeds of Topological Solitons in Nonlocal Josephson Electrodynamics

摘要

For the model [6] of nonlocal electrodynamics with nonsmooth (piecewise linear) nonlinearity, the problem of point spectrum of speeds of topological solitons with the minimal topological charge is analyzed. The variation of the spectrum of speeds under one-parameter deformation of such a nonlinearity is determined.
