The Property of Congruence on δ-lattice
WU Miao-ling · Mohu xitong yu shuxue · 2011
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.
