The lifespan of classical solutions to wave equations with weighted nonlinear terms in one space dimension

We consider the Cauchy problem for nonlinear wave equation with weighted nonlinear terms in one space dimension. When there is no weighted function in the nonlinear term, Zhou (1992) has obtained the sharp estimates of the lifespan. Kubo & Osaka & Yazici (2013) obtained the upper bound of the lifespan for the problem, however, the estimates is not sharp. The aim of this talk is to extend Zhou's result to our equations and establish sharp estimates of the lifespan.
