A Reduct Part of Relation Algebra and the Lattice of Deductive Systems
In this paper we concider a reduct part of relation algebras as residuated Lattice and investigate the residual operations through some theorems. We then define different types of deductive systems and give their properties together with some relations among them. We define the prime deductive system on a relation algebra and specify the differences between the definitions of deductive systems and prime deductive systems on lattice and relation algebra. Also the set Ds(A) is defined and investigated if it is a relation algebra.
Regarding indexing issue:
