Contrôlabilité approchée de l’équation de la chaleur semi- linéaire. (Approximate controllability for the semilinear heat equation). (French. Abridged English version) Zbl 0770.35009
Summary: This note is concerned with the study of the approximate controllability problem for the semilinear heat equation in a bounded domain \(\Omega\) with homogeneous Dirichlet boundary conditions when the control acts on any open and nonempty subset of \(\Omega\). The approximate controllability in \(L^ p(\Omega)\) for \(1<p<+\infty\) is proved when the nonlinearity is globally Lipschitz.
