| Research Abstract |
Abstract Strichartz estimates have been obtained for wave equations outside obstacles. As an application, the global (in time) existence of small solutions to semilinear wave equations with power-type nonlinear terms has been proved in 3-D domain outside obstacles.
Weighted space-time L^2 estimates have been also obtained for wave equations with space-time dependent variable coefficients. As an application, some new results on local (in time) wellposedness have been proved for quasilinear wave equations with low regularity radial data.
