Resumen de On a weakly hyperbolic quasilinear mixed problem of second order

Piero D'Ancona, Mariagrazia Di Flaviano

• We consider the mixed initial-boundary value problem for a second order hyperbolic quasilinear equation, degenerating at t = 0, and we prove the local well posedness in C°°. The main tools are a priori energy estimates and the Nash-Moser theorem.
