| Descripción |
: Rough relation algebras were introduced by S. Comer as a generalisation of algebras of Pawlak
's rough sets and Tarski's relation algebras. In this paper, some algebraic and arithmetical properties
of rough relation algebras are studied and the representable rough relation algebras are characterised.
1. Definitions and preliminary results
We assume that the reader is familiar with the basic facts of relation algebras as presented
e.g. in [4] or [8]. For Stone algebras the reader is invited to consult [2].
Rough sets and rough relations were introduced by Z. Pawlak ([10], [11]) arising from
his work on approximation spaces and information systems, and presented as an alternative
to fuzzy sets and tolerance theory. Rough relations can be thought of as an approximation
of relations via an equivalence relation on the base set when there is only incomplete
information. A description of the construction is given below. A lattice theoretic
approach to rough sets was taken by Iwinski [6], a...
