Аннотация:The Sedov variational principle, which is a generalization of the least-action principle for dissipative processes, and classical dissipative mechanics in the phase space are used. The main points of the quantum dissipative dynamics suggested in a recent paper are considered. As an example of a dissipative quantum theory, we discuss the nonlinear two-dimensional affine-metric sigma model. The conformal anomaly of the energy-momentum tensor trace for the closed bosonic string on the affine-metric manifold is investigated. The two-loop metric beta function for the nonlinear dissipative sigma model is calculated.
