Exact controllability to trajectories for semilinear heat equations with discontinuous diffusion coefficients. (English) Zbl 1092.93006
The authors investigate the exact controllability to trajectories for a transmission problem for semilinear heat equation. Transmission conditions on the interface and Dirichlet boundary conditions at the external part of the boundary are given. The system can be viewed as a semilinear heat equation with discontinuous diffusion coefficients. If the nonlinear term grows (at infinity) slower than $$|r|\log^{3/2}(1=|r|)$$, then the exact controllability to trajectories is proved for the case when the control acts in the region with the smaller diffusion coefficient. The proof is based on the null controllability results for the associated linear system and on global Carleman estimates.
