%0 Journal Article %T Analytic Extension of hyperharmonic numbers %A Istvan Mezo %J Online Journal of Analytic Combinatorics %D 2009 %I University of Auckland %X We define the analytic extension of hyperharmonic numbers involving the Pochhammer symbol, gamma and digamma functions. In addition, some sum of hyperharmonic series have been calculated. Surprisingly, the Lerch transcendent appears in the closed form of the sums. %U http://analytic-combinatorics.org/index.php/ojac/article/view/53
