The lifespan estimates of classical solutions of one dimensional semilinear wave equations with characteristic weights
Abstract
In this paper, we study the lifespan estimates of classical solutions for semilinear wave equations with characteristic weights and compactly supported data in one space dimension. The results include those for weights by time-variable, but exclude those for weights by space-variable in some cases. We have interactions of two characteristic directions.
