On the exact boundary controllability of semilinear wave equations

Sue Claret, Jérôme Lemoine, Arnaud Münch

We address the exact boundary controllability of the semilinear wave equation ${\partial }_{tt}y-\Delta y+f(y)=0$ posed over a bounded domain $\Omega$ of ${\mathbb{R}}^d$. Assuming that $f$ is c…
