The sole motivation behind this work is to study the notions of fuzzy sets, rough sets and intuitionstic fuzzy sets, to explore as well as to formulate the fuzziness and roughness occurring within the framework of a number of mathematical avenues, and hence to promote some fuzzy and rough mathematical theories along with a few extensions in some existing frameworks.
