Pointless Form of Rough Sets FEIZABADI, ABOLGHASEM KARIMI; ESTAJI, ALI AKBAR; ABEDI, MOSTAFA;
In this paper we introduce the pointfree version of rough sets. For this we consider a lattice L instead of the power set P(X) of a set X. We study the properties of lower and upper pointfree approximation, precise elements, and their relation with prime elements. Also, we study lower and upper pointfree approximation as a Galois connection, and discuss the relations between partitions and Galois connections.
