摘要
研究了六变元变系数非齐次超双曲型方程齐次Dirichlet问题,给出了它的存在唯一性定理。得到了一类高维非齐次超双曲型方程齐次Dirichlet问题的存在唯一性定理。
In this paper, the homogeneous Dirichlet problem of six—variable coefficient inhomogeneous ultra—hyeprbolic equation is discussed and the theorem of the propertics of unique and existence is given, In the second part, the homogeneous Dirichlet problem of multivariate ultra—hyperbolic equation is considered
