✦ Synopsis

Previous results have demonstrated that umqueness for the mltlal-value problem for partlal differential equations with multiple charactenstxs holds If the subprmclpal symbol does not vamsh on the mulnply charactenstlc set (real or nonreal) It IS shown m tl-ns paper that for equations with double charactenstics, uniqueness depends only on the hyperbohc pdrt of the equation, the real charactenstlcs
