Abstract:

In an earlier work of the author it was proved that the Strichartz estimates for second order hyperbolic operators hold in full if the coefficients are of class $C^2$. Here we strengthen this and show that the same holds if the coefficients have two derivatives in $L^1(L^\infty )$. Then we use this result to improve the local theory for second order nonlinear hyperbolic equations.
