Mengyun Liu, Chengbo Wang

摘要:

研究了$n$维非捕获渐近欧氏流形上具有幂型非线性项和一般低阶项的半线性波动方程解的整体存在性,当$n=3, 4$ .此外,我们证明了四维临界问题的几乎整体存在性和尖锐的下界的寿命。

英文摘要:

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.
