In this article some necessary conditions in order for the Cauchy problem for hyperbolic systems to be well posed will be studied. In the scalar case, from Ivrii-Petkov [1], for the well-posedness of the Cauchy problem, a set of vanishing conditions on the lower order terms must be verified at a multiple characteristic. Our purpose is to find some necessary conditions which correspond to the Ivrii-Petkov conditions for systems. In [2], we obtained a necessary condition in this direction. Here we continue this study.
