Riemann's Zeta Function: The alternating Xi-Function Xia(s)

Number Theory 2016-10-24 v2

Abstract

As well known, the study of Riemanns zeta function {\zeta}(s) involves the related entire function {\xi}(s). A close relative of {\zeta}(s) is the alternating zeta function {\eta}(s). Similar to {\zeta}(s), also {\eta}(s) has a corresponding entire function {\xi}_a (s). After establishing its definition and a related functional equation, formulas based on incomplete gamma functions are worked out, allowing to numerically evaluate {\xi}_a (s). Examples verifying the obtained formulas are included.
