泛半等价关系

PAN—SEMI—EQUIVAENT RELATION

本文中,首次定义了泛关系、泛半等价关系、泛等价关系及双层映射等概念,并讨论了泛半等价关系的一些性质。在此基础上,研究了泛半等价关系与泛等价关系之间的联系,并给出了求泛半等价关系的传递闭包的简便方法。

In this Paper, Concepts of pan—rolation, Pan—Somi—equivalent relation, pan—egujualent rolation,and double mapping are dofincd,and Some Properties of Pan—Somi—oguivalent rolation are discussed,On this basis the ties between Pan—Somi—eguivalent velation and Pan—eguivalent rolation are studied,and a simple algorithm for determing thetrasitire Closure of a Pan—Somi—eguivalent velation is givon.
