Necessary and sufficient conditions for oscillations of parabolic partial differential equations
【摘要】 讨论一类多滞量抛物型时滞偏微分方程解的振动性质,获得了其一切解振动的充要条件及一些充分条件;指出了其与普通抛物型偏微分方程解的质的差异.
【Abstract】 In this paper, oscillatory properties of solutions of certain parabolic partial differential equations are investigated. A series of necessary and sufficient and a series of sufficient conditions for oscillations of the equations are established.
