  A general algebraic method of quantum corrections evaluations is presented.
Quantum corrections to a few classical solutions of Landau-Ginzburg model
(phi-in-quadro) are calculated in arbitrary dimensions. The Green function for
heat equation with soliton potential is constructed by Darboux transformation.
The generalized zeta-function is used to evaluate the functional integral and
corrections to mass in quasiclassical approximation. Some natural
generalizations for matrix equations are discussed in conclusion.
