- We investigate the lifespan of quasilinear Dirichlet-wave equations of the form (lower case delta squared subscript t - Delta) u = Q(u,u prime,u prime prime) in [0,T] times R superscript3 backslash K, where K is a bounded domain with smooth boundary. Previous results have demonstrated long time existence in the case that K was assumed to be star-shaped. We show that the same lifespan holds for more general geometries, where we only assume a polynomial local decay of energy with a possible loss of regularity for solutions to the linear homogeneous wave equation.
