"Fuzzy Mathematical Concepts" deals with the theory and applications of Fuzzy sets, Fuzzy relations, Fuzzy logic and Rough sets including the theory and applications to Algebra, Topology, Analysis, probability, and Measure Theory. While the first two chapters deal with basic theory and the prerequisite for the rest of the book, readers interested in Algebra and Logic may go through chapters 3 and 4, those interested in Topology may proceed to chapters 5 to 8 and for Analysis one may read chapters 8 and 9. Readers interested in Rough Set Theory may directly proceed to chapter 10 after completing chapters 1 and 2. A part of the book can be covered in one semester depending on the requirement and the whole book in two semesters.
