As quantitative generalizations of Pawlak rough sets, probabilistic rough sets probabilistic rough set consider degrees of overlap between equivalence classes and the set. An equivalence class is put into th
We define subclasses of the class of all disjoint k-tuples of NP-sets. These subclasses are associated with a propositional proof system and possess complete tuples which are defined from the proof system. In our main result we show that complete disjoint NP-pairs exist if and only if ...

Several studies on rough set approximation maps that are determined by binary relations reflecting distinguishability or indistinguishability of the elements of the universe of discourse can be found in the literature (see e.g. [11] for further references). For instance, E. Orłowska and Z. Pa...
The covering-based rough set system C2 is indeed categorically equivalent to the rough set system based on reflexive and transitive relations. 2. Kripke and covering structures The language of modal logic LML consists of a denumerable set of propositional variables Prop, propositional connectives ¬...
(such as union, intersection), the cardinality of a set and relations, etc. some of the basic concepts involved in set theory are as follows: universal set a universal set is usually denoted by the capital letter ‘u’. also, sometimes it is denoted by ε(epsilon). it is a set ...
