On the Normal Semilinear Parabolic Equations Corresponding to 3D Navier-Stokes System

摘要

The semilinear normal parabolic equations corresponding to 3D Navier-Stokes system have been derived. The explicit formula for solution of normal parabolic equations with periodic boundary conditions has been obtained. It was shown that phase space of corresponding dynamical system consists of the set of stability (where solutions tends to zero as time t →∞), the set of explosions (where solutions blow up during finite time) and intermediate set. Exact description of these sets has been given.
