Quasilinear wave equations and Strichartz estimates. (Équations d’ondes quasilinéaires et estimations de Strichartz.) (French) Zbl 0952.35073

The authors present an existence result for a certain class of quasilinear wave equations where the initial data are less regular than those required by energy methods. The main theorem is similar to a previous result established by G. Ponce and T. Sideris only for semilinear wave equations. The proof needs Strichartz estimates for wave operators whose coefficients are only Lipschitz continuous.
