内容摘要:

We study the global existence of solutions to semilinear wave equations with power-type nonlinearity and general lower order terms on n dimensional nontrapping asymptotically Euclidean manifolds, when n=3, 4. In addition, we prove almost global existence with sharp lower bound of the lifespan for the four dimensional critical problem.
