摘要
本文考虑具有偏差变元的抛物型微分方程强迫振动性.给出了某些边值问题的所有解在柱形区域内振动的若干充分条件,所得结果推广和改进了文献中的一些熟知的结果.
In the present paper,forced oscillations of parabolic differential equations are studied and sufficient conditions are given for all solutions of some boundary value problems to be oscillatory in a cylindrical domain. Our theorems extend and improve some of the known results in the literature.
