讨论余Quantale的一些性质,引入预余Quantale的概念并给出预余Quantale成为余Quantale的充要条件,构造了一些子余Quantale结构。
In this paper, some basic properties of co-quantale are discussed. The notion of precoquantale is introduced,two sufficent and necessary conditions that preco-quantale turn into co-quantale are obtained. Also,some subco-quantales are given.
