摘要
In this paper, we consider exact controllability to trajectories for a semilinear heat equation with nonlinearity that has superlinear growth at infinity with Dirichlet boundary conditions in a bounded domain of a"e (N) . The results are established by using the variational methods, the related duality theory and Kakutani Fixed-point Theorem and generalize the previous results.
