| Abstract: | This paper discusses how to determine the low term coefficient q(x) in the inverse problem of Cauchy problem of hyperbolic type equation ua(x,t) - u22(x,t)+p(x)ux(x,t)+q(x)u(x,t) = F(x,t). The uniqueness and existence for local solution of the inverse problem are given in this paper. |
