Global existence for fully parabolic boundary value problems

We present some results on the global existence of classical solutions for quasilinear parabolic equations with nonlinear dynamic boundary conditions in bounded domains with a smooth boundary.     

On the Solvability of Double Degenerate Quasilinear Parabolic Equations

We deal with the existence of solutions for double degenerate quasilinear parabolic equations which can degenerate, on a part of the boundary, on a segment in the interior of the domain and in time. This revised version was published online in June 2006 with corrections to the Cover Date.     

Insensitizing controls for a class of quasilinear parabolic equations

This paper is addressed to showing the existence of insensitizing controls for a class of quasilinear parabolic equations with homogeneous Dirichlet boundary conditions. As usual, this insensitizing problem is reduced to a nonstandard null controllability problem of some nonlinear cascade system governed by a quasilinear parabolic equation and a linear parabolic equation. Nevertheless, in order to solve the later quasilinear controllability problem by the fixed point technique, we need to establish the null controllability of the linearized cascade parabolic system in the framework of classical solutions. The key point is to find the desired control function in a Hölder space for given data with certain regularities.
