Counterexamples to well posedness for some hyperbolic operators with triple characteristics

Enrico Bernardi, Tatsuo Nishitani

In this paper we prove that for a class of non-effectively hyperbolic operators with smooth triple characteristics the Cauchy problem is well posed in the Gevrey 2 class, beyond th…
