摘要
本文借助弱射影和弱透视的概念刻划了ＤｅＭｏｒｇａｎ代数的同余关系。
In this paper characterizations of congruences of De Morgan algebras are given by the notion of weak projectivity and from these we derive that the congruence relations of the completely distributive De Morgan algebra L are in a one to one correspondence with congruence ideals of L if and only if L is weakly complemented.
