摘要
本文讨论一阶奇性拟微分方程的Cauchy问题解的唯一性.其中A,B∈P_s(?)~1.首先证明了算子P的一个Carleman估计,然后利用经典的讨论,证明奇性Cauchy问题的唯一性.
In this paper, the uniqueness of the first order singular pseudo-differential equationis discussed, where P = tDt+tlA+iB, A,B∈OPS11,0 First, the author proves aCarleman estimate of operator P, then the uniqueness of the singular Cauchy problem is also proved by a classical arqument.
