Résumé: 
PM  EDP  The combined effect of one space dimension beyond the general theory for nonlinear wave equations  
Description: 
Takiko SasakiIn this talk, we show the socalled “combined effect” of two different kinds of nonlinear terms for semilinear wave equations in one space dimension. Such a special phenomenon appears only in case the total integral of the initial speed is zero. It is remarkable that, including the combined effect case, our results on the lifespan estimates are partially better than those of the general theory for nonlinear wave equations. This is a joint work with Prof. H. Takamura and Mr. K. Morisawa.
