| Abstract: |
| In this talk, we mainly introduce the controllability of several types of nonlinear wave equations. Firstly, by using the Galerkin method, we obtain the null controllability of a class of semilinear wave equations. Secondly, based on the Picard iteration method, we establish the local null controllability of a class of quasilinear equations. The talk is based on joint work with Peng Lu and Yi Zhou. |
