On the series expansion of a square-free zeta series

Abstract

In this article, we develop a square-free zeta series associated with the Möbius function into a power series, and prove a Stieltjes like formula for these expansion coefficients. We also investigate another analytical continuation of these series and develop a formula for $\zeta (\frac{1}{2})$ in terms of the Möbius function, and in the last part, we explore an alternating series version of these results.
