Let D be a distributive lattice, and let L be a frame. In this article, we introduce the notion of L-ideals of D. We show that the set of all L-ideals of D is a distributive lattice, and some essential properties of this lattice are studied. Also, we discuss some special elements of this lattice. Moreover, we define a novel congruence relation for the concept of L-ideal of D. Finally, we study some properties of rough sets inherited from the congruence relation.

L理想和基于L理想的粗糙集

D为分布晶格,令L为框架。在这篇文章中,我们介绍的概念大号的-ideals d。我们发现,所有带大号的-ideals d是一个分配格,这格的一些基本特性进行了研究。另外,我们讨论了该晶格的一些特殊元素。此外,我们为DL理想概念定义了一个新颖的等价关系。最后,我们研究了从同余关系继承的粗糙集的一些性质。
