Diffusion Convection Equation with Variable Nonlinearities

الملخص EN

The paper studies diffusion convection equation with variable nonlinearities and degeneracy on the boundary.

Unlike the usual Dirichlet boundary value, only a partial boundary value condition is imposed.

If there are some restrictions in the diffusion coefficient, the stability of the weak solution based on the partial boundary value condition is obtained.

In general, we may obtain a local stability of the weak solutions without any boundary value condition.
