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 {\cal G}(\omega,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 {\cal G}(\omega,k_x,k_y,k_z,z) determines quantization of Hall conductivity in the soliton plane within the topological insulators.
