报告摘要：Orthomodular lattices have been consideredas a mathematical model for a calculus of quantum logic. Effect algebras are ageneralization of Orthomodular lattices and are also regarded as a mathematicalmodel of quantum logic. A lattice effect algebra, is an effect algebra E whichis a lattice with respect to the partial ordering induced by the operation ofE. Now in this talk, first we introduce the notion of lattice effect algebrasand we give some of its properties. Then we define some types of filters inlattice effect algebras, investigate some relations between them and introducesome new examples of lattice effect algebras. Then by using the strong filter,we find a CI-lattice congruence on lattice effect algebras, such that theinduced quotient structure of it is a lattice effect algebra, too. Finally,under some suitable conditions, we get a quotient MV-effect algebra and aquotient orthomodular lattice, by this congruence relation.
