摘要
本文获得了双曲型方程组在齐次Neumann,Dirichlet和Robin边值条件下,所有解振动的充分条件.
In this paper, sufficient conditions are obtained for the oscillation of all solutions of the homogeneous Neumann, Dirichlet and Robin's boundary value problems associated with the hyperbolic system
for i = 1, 2, ???, m, (x, t) € ft x (0, oo), $1 C Rn, where A denotes the Laplacian in E'.
