Quotient mean series

Abstract

The well-known Mathieu seriescan be transformed into the formwhere G(n, r) and Q(n, r) denote the Geometric and Quadratic mean of n ∈ N and r > 0. This connection leads us to the idea to introduce and research the so-called Quotient mean series as a be a generalizations of Mathieu's and Mathieu-type series. We give an integral representation of such series and their alternating variant, together with associated inequalities. Also, special cases of quotient mean series, involving Bessel function of the first kind, have been studied in detail.
