Abstract
The Goursat problem for certain types of second order linear equations is considered. The Goursat problem for those second order equations is not -wellposed in general. For a certain type homogeneous equations, the Goursat problem is -wellposed. Necessary or sufficient conditions on lower order terms for -wellposedness are given. Wellposedness in Gevrey class is discussed.
