把粗糙集理论方法应用到Leibniz代数上,定义了Leibniz代数上的同余关系,给出了Leibniz代数的粗糙子代数和粗糙理想等概念,研究了Leibniz代数上粗糙集在同态映射下的若干性质。
In this paper, we introduce the idea of rough sets on Leibniz algebras, define a congruence relationship in a Leibniz algebra, give the concepts of rough subalgebra and rough ideal and study some properties of rough sets under the homomorphism of a Leibniz algebra.
