摘要
指出δ格并既约元集中极小元在商的弱射影中的作用,证明了δ格上成立的一些等价条件和δ格是简单格的充分必要条件,说明了弱射影与主既约商的关系以及δ格与布尔代数的关系。
The function of the minimal element in the join-irreducible elements of the weak projection of quotient on δ-lattice is pointed.Some equivalent conditions are in any δ-lattice are given.The necessary and sufficiency whether δ-lattice is simple lattice is also proved.What is more,the relation between the weak projection and the irreduciblequ is given.The relation between the δ-lattice and the Boole lattice is also given.
