中立型高阶偏微分方程解的振动性与渐近性
Oscillations and Asymptotic Property of High Order Neutral Partial Differential Equations
【摘要】 本文研究了一类中立型高阶偏微分方程在第一和第三边值条件下解的振动性质,得到了方程所有解u(x,t)振动或者limt→+∞乙赘u(x,t)dx=0的一些充分性判别准则。
【Abstract】 Under the first bound condition and the third bound condition, the oscillatory property of high order neutral partial differential equations are discussed. Some sufficient conclusions are obtained that all solution u(x,t) of the equation is oscillatory or u(x,t)dx=0.
