Explicit estimates on a mixed Neumann-Robin-Cauchy problem

Explicit estimates on a mixed Neumann-Robin-Cauchy problem

We deal with the existence of weak solutions for a mixed Neumann Robin Cauchy problem. The existence results are based on global-in-time estimates of approximating solutions, and the passage to the limit exploits compactness techniques. We investigate explicit estimates for solutions of the parabolic equations with nonhomogeneous boundary conditions and distributional right-hand sides. The parabolic equation is of divergence form with discontinuous coeffi- cients. We consider a nonlinear condition on a part of the boundary such that the power laws (and the Robin boundary condition) appear as particular cases.
