Abstract
Purpose - The purpose of this paper is to propose an approximate method for solving a fractional population growth model in a closed system. The fractional derivatives are described in the Caputo sense.
Design/methodology/approach - The approach is based on the differential transform method. The solutions of a fractional model equation are calculated in the form of convergent series with easily computable components.
Findings - The diagonal Pade approximants are effectively used in the analysis to capture the essential behavior of the solution.
Originality/value - Illustrative examples are included to demonstrate the validity and applicability of the technique.
