报告摘要:

We study a class of quasilinear systems of PDE displaying strong instability properties in spite of having real (multiple) characteristic roots at initial time. We provide a geometric construction of instable solutions at the boundary of the elliptic and hyperbolic domains and we shall give several explicit examples.
