Fractal derivatives, fractional derivatives and $q$-deformed calculus [PDF]

Entropy 2023, 25(7), 1008, 2023
This work presents an analysis of fractional derivatives and fractal derivatives, discussing their differences and similarities. The fractal derivative is closely connected to Haussdorff's concepts of fractional dimension geometry. The paper distinguishes between the derivative of a function on a fractal domain and the derivative of a fractal function,
