Regardless of the types of fractional-order derivatives, Fractional Differential Equations (FDEs) have been recently applied in modeling various phenomena in natural sciences and engineering. From the scientific literature of fractional-order derivatives or fractional calculus, there were historically known as integer-order calculus but not much interest among mathematicians at that time to discover the advantages of research studies on fractional calculus. My question is according to my knowledge why there is no courses in the area of fractional differential equations (FDEs) exist at any university or college. A course on this field of research will be very beneficial for graduate students who interested in doing further studies on fractional derivatives. Please share your thoughts if you aware of any courses exist in this area of research and could you please share the links to the course so every researcher can benefit from that. I would greatly appreciate all your comments and discussion regarding this important question!!
