非R．N．A．型泛函微分方程的近期进展

泛函微分方程除了滞后型，中立型，超前型三类以外，还有很多特别型式的方程类，这些方程类有它们自己的应用背景和完全不同的问题提法，是现有泛函微分方程理论所不能概括的，我们把它统称为“非Ｒ．Ｎ．Ａ”型泛函微分方程”。

Some Developments of Non-"R.N.A.Type"Functional Differential Equations

In addition to retarded,neutral,advanced type functional differential equations have may other spotal equational type.These equational types have their own application backgrounds and totally different methods of raising problems.They can't be involved in the existing thenes of functional differential equations.In this paper,we summerise the general situation of the recent development of these equations and some results of our study in the field,which inVolve the methods of building these type equations and give various representive equations,the methods of the Cauchy ptoblems of some spotal equations and the analytic solutions of one type of complicated deviating arguments.In addition to that we give a general classification in order to make our discussion convenient.
