“集合分类与等价关系”新讲

New Lectures on"Partition and Equivalence Relation"

"集合分类与等价关系"是《近世代数》课程中一个非常重要的知识点,不仅对学习商群、环、局部化等概念有很大帮助,还是构造新的代数对象的手段之一.文章就如何让学生更深入理解和掌握该知识点进行了探讨.

We know that ＂Partition and Equivalence Relation＂ is one of the most important contents of Abstract algebra . It is not only helpful to learning the concepts of quetient group, ring, localization, and so on, but also one of the tools of constructing new algebra objects. In this paper, we investigate how to give lectures so as to let students understand more deeply.
