中立型抛物型微分方程组的振动性

摘要

讨论中立型抛物型微分方程组的解的振动性质，我们得到了中立型抛物型微分方程组在两类边界条件下所有解振动的充分条件。%　　This paper researches on the problem of oscillation for the system of parabolic equations of neutral type .Suffi-cient conditions are obtained for the oscillations of all solutions of the system of parabolic equations of neutral type under two class boundary conditions.
