齐次超双曲型方程的特征问题

The Characteristic Problem of Homogeneous Ultrahyperbolic Equations

给出了一类齐次超双曲型方程的广义Ａｓｇｅｉｒｓｓｏｎ中量定理，证明了该类方程特征问题的解的存在性和唯一性．

in this article,the exitence and uniquenase of characteristic solution of homogeneousultrshyperbotic equations of arbitrars variation are aboved by using generalized Asgeiresson meanvalue theorem.
