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, k_x, 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, k_x, k_y, k_z, z) determines quantization of Hall conductivity in the soliton plane within the topological insulators.
