报告题目：On Filter Theory of LatticeEffect Algebras

报 告 人：Prof. Dr. Rajab Ali Borzooei

报告摘要：Orthomodular lattices have beenconsidered as a mathematical model for a calculus of quantum logic. Effectalgebras are a generalization of Orthomodular lattices and are also regarded asa mathematical model of quantum logic. A lattice effect algebra, is an effectalgebra E which is a lattice with respect to the partial ordering induced bythe operation of E. Now in this talk, first we introduce the notion of latticeeffect algebras and we give some of its properties. Then we define some typesof filters in lattice effect algebras, investigate some relations between themand introduce some new examples of lattice effect algebras. Then by using thestrong filter, we find a CI-lattice congruence on lattice effect algebras, suchthat the induced quotient structure of it is a lattice effect algebra, too.Finally, under some suitable conditions, we get a quotient MV-effect algebraand a quotient orthomodular lattice, by this congruence relation.
