Stabilization of the solution to a heat equation in the exterior of a sphere with boundary control
A. V. Gorshkov Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
The problem of boundary control stabilization of the solution to the heat equation defined in the exterior of a sphere is studied in the paper. The boundary control function stabilizing the solution to zero with the rate $ 1/{t^k}$ is constructed for any $k>0$.
Key words:
heat equation, exterior Dirichlet problem, stabilizability, Bessel functions, Bessel–Fourier integral, spherical functions.
