Null controllability of degenerate parabolic equations in non divergence form via Carleman estimates. (English) Zbl 1258.93025
Summary: We prove null controllability results for the one dimensional degenerate heat equation in non divergence form with a drift term and Neumann boundary conditions. To this aim, we prove Carleman estimates for the associated adjoint problem. Some linear extensions are considered.
