Abstract:  By employing the Bose and Fermi distribution functions, we introduce a method to calculate the summation of an infinite series via the residue calculus. With this method we obtain several infinite series sums and further derive the Mittag-Leffler expansions of some important functions.

Key words: residue calculus, Bose distribution function, summation of infinite series, Mittag-Leffler expansion
