摘要
The aim of the paper is to consider a Cauchy problem related to the class of hyperbolic operators with double characteristics in the half-space Omega = R-2 x] 0,+infinity[. A priori estimates in Sobolev spaces W-r,W-2, with r negative, are shown. Moreover, an existence and uniqueness result is presented.
