O Cálculo Fracionário aplicado à modelos matemáticos clássicos

Abstract

This work presents a study on non-integer order calculus, known as Fractional Calculus, applied to classical mathematical models. It was observed that replacing the usual derivative of an ordinary differential equation by a fractional derivative according to Caputo of lower order than the original problem, the solution behavior of three of the four models studied showed a decrease in the rate of variation. On the other hand, for the last model examined, namely the Malthusian Population Growth model, reducing the order of the problem resulted in a solution with a higher rate of change.
