摘要：The blow-up phenomenon is one of the main concerns in nonlinear wave equations. For the focusing semilinear wave equations, given any compact set in R^n, we construct finite energy solutions which blow up at finite time exactly on E. Related blow-up surface results will be also introduced. This talk is based on joint works with Thierry Cazenave and Yvan Martel.
