Null controllability for linear parabolic cascade systems with interior degeneracy

Blog Article

We study the null controllability problem for linear degenerate parabolic systems with one control force through Carleman estimates for the associated adjoint problem.The novelty of this article is that for the first time it Diabetes Care is considered a problem with Sectional an interior degeneracy and a control set that only requires to contain an interval lying on one side of the degeneracy points.The obtained result improves and complements a number of earlier works.As a consequence, observability inequalities are established.
