【摘要】 本文提出了两个函数积分与测度为正，Ｖ泛函范数渐小与积分渐小的概念，并给出了满足这些概念的简捷条件，依此建立了中立型泛函微分方程解的渐近性与稳定性的几个基本定理。这些定理统一，改进与推广了一些相关的经典结果。更多还原

【Abstract】 This paper proposes concepts of integral (or measurable) positivity of a function on another one and integral (or norm) decrescent property of a V-functional. Simple sufficient conditions for satisfying these concepts are given.Based on the above concepts,we obtain several fundamental theorems for stability and asymptotic property of solutions of neutral functional differential equations.These theorems unify, improve and extend some relevant classical results.更多还原
