Controllability of a system of non-autonomous degenerate coupled parabolic equations

Analysis of PDEs 2025-08-26 v1

Abstract

We prove a Carleman estimate for a one-dimensional parabolic equation which degenerates at one extremity of the domain and has a bounded, time dependent coefficient multiplying the diffusion term. Then we use the estimate to show the null controllability of a coupled system characterized by this form of diffusion operator and bounded coefficients.
