The main goal of this paper is to explicate and explain connections between neoclassical analysis and fuzzy set theory. To this goal, we consider here fuzzy sets of derivatives and intuitionistic fuzzy sets of derivatives of real functions. Neoclassical analysis may be treated as a new direction...

The main goal of this work is the further development of neoclassical analysis, which extends the scope and results of the classical mathematical analysis by applying fuzzy concepts to conventional mathematical objects, such as functions, sequences, and derivatives. This allows us to reflect and...
