Abstract

Topological invariants in terms of the Green's function in momentum and real space determine properties of smooth textures within topological media. In space dimension d = 1 the topological invariant N3 in terms of the Green's function [InlineMediaObject not available: see fulltext.](ω, kx, x) determines the fermion number of the kink, while in space dimension d = 3 the topological invariant N5 in terms of the Green's function [InlineMediaObject not available: see fulltext.](ω, kx, ky, kz, z) determines quantization of Hall conductivity in the soliton plane within the topological insulators.
