Approximation of null controls for semilinear heat equations using a least-squares approach

Jerome Lemoine, Irene Marin-Gayte, Arnaud Munch

The null distributed controllability of the semilinear heat equation $y_t-\Delta y+g(y)=f{1}_{\omega }$, assuming that $g$ satisfies the growth condition $g(s)/(\vert s\vert \log^{3/2}(1+\ver…
