Algebras and Logics Emerging Out of Rough Sets (An Invited Review Paper)

Abstract

This is basically a survey work though some new results have also been incorporated. The contents presented are from the research done by Chakraborty and his co-workers for last three decades. A major part consists in presentation of set-models of abstract algebraic structures generated from rough sets. Three Types of logics developed during the course of research are categorized. Some foundational issues are raised at the end and open questions are mentioned.
