Title：The lifespan estimates of classical solutions of one dimensional semilinear wave equations with characteristic weights.

Abstract：In this talk, we will discuss the lifespan estimates of classical solutions for semilinear wave equations with characteristic weights and compactly supported data in one space dimension. Our results include those with weights by time-variable, but exclude those with weights by space-variable in some cases. We also remark that there is an interaction among two characteristic weights in the lifespan estimates. This talk is based on a joint work with Profs. Hiroyuki Takamura (Tohoku Univ.) and Kyouhei Wakasa (National Institute of Technology, Kushiro College).
