On the Stieltjes constants with respect to harmonic zeta functions

Abstract: The aim of this paper is to investigate harmonic Stieltjes constants occurring in the Laurent expansions of the function [ \zeta_{H}\left( s,a\right) =\sum_{n=0}^{\infty}\frac{1}{\left( n+a\right) ^{s}}\sum_{k=0}^{n}\frac{1}{k+a},\text{ }\operatorname{Re}\left( s\right) >1, ] which we call harmonic Hurwitz zeta function. In particular evaluation formulas for the harmonic Stieltjes constants $\gamma_{H}\left( m,1/2\right) $ and $\gamma_{H}\left( m,1\right) $ are presented.
