- These papers aim to investigate the distribute of rfde with delays and the asymptotic behavior of its solutions
本文就时滞微分系统特征根的分布及其解的渐近行为作了一些研究，并得出了一些结论。 - A brief description of the organization of this paper follows . there are four chapters in this paper . in the first chapter , by using the character of operator d and liapunov functional , we deal with the stability of solutions of linear nfde of d - operator type with infinite delay , generalize the results of rfde
基于这类方程的复杂性，可以讨论具体的volterra方程。本论文共分四章。第一章利用d算子的性质及liapunov泛函讨论了无穷时滞d算子型fde的稳定性，推广了一般泛函微分方程的结论。 - Fde and dde have been extensively developed since 1959 , and each branch has been set up a complete theory system . now , more and more scholars study fde and explore further developments . also , fde with infinite delay is one of the fields of great interest to people . in fact , fde with infinite delay has undergone a rapid development since 1870s . hale and kato gave a normal and set up the b phase space theory in 1978 . under the basic theory , people studied the stability , boundedness and periodic solution of rfde . for example : in [ 4 ] , huang qichang introduced the concept of uniformly forgetful functional , discussed the boundedness and stability of solution ; [ 5 ] - [ 8 ] discussed the existence of periodic solutions , generalized the results of rfde with finite delay . however , for nfde with infinite delay , few people discuss it , and many problems have not been solved . so there are some very interesting developments . lt is worth while generalizing the results of fde with fini te delay or rfde with infinite delay to nfde with infinite delay . because of the difficulty of infinite delay , we may discuss neutral volterra integro - differential equations , and obtain simple results
自1959年以来，无论是一般的泛函微分方程还是具体的微分差分方程，其发展是非常迅速的，在每一分支中都形成了一套完整的理论体系，如今越来越多的学者涉足这一领域探求更新的发展，无穷时滞泛函微分方程就是他们研究的主要对象之一。准确地说，无穷时滞泛函微分方程兴起于19世纪七十年代， 1978年hale与kato提出b空间的公理体系。在此体系下建立了方程的基本理论，并研究了解的稳定性、有界性、周期解等问题，如[ 4 ]利用一致健忘的liapunov泛函讨论了解的有界性和稳定性， [ 5 ] - [ 8 ]讨论了周期解的存在性，推广了有限时滞的相关结果。
