报告摘要:I will talk about long time existence problem of semi-linear Klein-Gordon equations on the circle. We shall show, that if the nonlinearity satisfying a convenient condition, then the solution, if it is even or odd about the space variable, must exist almost globally, for almost every positive mass. The requirement that the solution is even or odd about the space variable can be removed if one strengthens the condition on the nonlinearity. The results are based on the method of normal forms. This is joint work with D.Y. Fang and Z. Han.
