Weakly Hyperbolic Systems by Symmetrization
F. Colombini, T. Nishitani, J. Rauch
We study hyperbolic first order systems and propose a new method proving Gevrey well posedness, constructing a symmetrizer, motivated by a special Lyapunov function for linear ODE.…

The Cauchy Problem for Wave Equations with NonLipschitz Coefficients
Ferruccio Colombini, Guy Metivier
In this paper we study the Cauchy problem for second order strictly hyperbolic operators when the coefficients of the principal part are not Lipschitz continuous, but only "Log-Lip…
