Controllability of degenerate and singular parabolic problems: the double strong case with Neumann boundary conditions

Abstract

We prove a null controllability result for a parabolic problem with Neumann boundary conditions. We consider non smooth coefficients in presence of a strongly singular potential and a strongly degenerate coefficient, both vanishing at an interior point. This paper concludes the study of the Neumann case.
