| Abstract: | The uniqueness, in the distrubutions, of solutions of the Cauchy problem for a class of degenerate hyperbolic second order equations is studied under the initial curve containing a doubly characteristic point. The techniques employed are Careleman estimates and concatenation methoed. |
