Rough Sets and 3-valued Lukasiewicz Logic
Mohua Banerjee · Fundamenta Informaticae · 1997
A propositional logic for rough sets was proposed in [2]. The present work establishes a relationship between the finitary fragment of this logic and 3-valued Lukasiewicz logic ℒ3. It is also observed that there is an embedding from ℒ3 into the modal system S 5 .
