Some problems of the qualitative theory of nonlinear degenerate second- order parabolic equations. (English) Zbl 0642.35047

A survey on modern theory of degenerate parabolic equations of the form u t =F(x,t,u,u x ,u xx )·

Investigations on such equations are important, because the equation of non-Newtonian filtration, the equation of rapid diffusion, the equations of nonlinear heat conduction and some other ones contain degeneracies.

The principal objects of investigation are generalized solutions. Chapter 1 is discussing problems of their existence and uniqueness. Estimates and regularity problems are considered in chapter 2. Short time and long time behavior of solutions is described in chapters 3 and 4. A list of about 300 references is presented.
