Abstract

In two previous works we improved some earlier results of Imanuvilov, Li and Zhang, and of Zuazua on the boundary exact controllability of one-dimensional semilinear wave equations by weakening the growth assumptions on the nonlinearity. Our growth assumption is in a sense optimal. Here we adapt our method for the case of one-sided control actions. This also enables us to obtain rather general internal controllability results.

具有无限迭代对数的半线性波动方程的可控性

在前两篇文章中，我们通过弱化非线性的增长假设，改进了Imanuvilov、Li和Zhang以及Zuazua关于一维半线性波动方程边界精确可控性的一些早期结果。我们的增长假设在某种意义上是最优的。在这里，我们对单侧控制动作的情况调整了我们的方法。这也使我们能够获得相当一般的内部可控性结果。
