Three Lessons on the Topological and Algebraic Hidden Core of Rough Set Theory,ology and algebraic logic..Many algebraic aspects of Rough Set Theory, are known nowadays. Other are less known, although they are important, for instance because they unveil the “epistemological meaning” of some “unexplained” mathematical features of well-known algebraic structures..We shall wrap e

Irredundant Coverings, Tolerances, and Related Algebras,scourse. We consider especially tolerances induced by irredundant coverings of the universe .. This is natural in view of Pawlak’s original theory of rough sets defined by equivalence relations: any equivalence . on . is induced by the partition .∕. of . into equivalence classes, and .∕. is a specia

Algebraic Representation, Dualities and Beyond,d, new proofs have been proposed, open problems are specified and new directions are suggested. Some recent duality results in the literature are also adapted for use in rough contexts. New results are also proved on granular connections between generalized rough and L-fuzzy sets by the present auth

Rough Objects in Monoidal Closed Categories, manipulation in general can be enriched by extending constructions to work similarly over monoidal closed categories embracing both algebraic as well as order structures. The chapter will also show how the rough information model in this monoidal closed category extension connects with other inform
