Mixed problem for degenerate nonlinear ultraparabolic equation

Nataliya Protsakh


This article describes the solvability of mixed problem for
nonlinear ultraparabolic equation with degeneration. The result is
obtained in the cases of the weak and the strong degenerations.
The conditions of solvability depend on the relations between the
coefficients of the equation and the parameter of degeneration.
