Limit Formulas Related to the p-Gamma and p-Polygamma Functions at Their Singularities

Abstract

In this paper, we mainly give much simple proof to Theorem 1.1 and (1.6) of Theorem 1.2 posed in the paper "Qi, F., \emph{Limit formulas for ratios between derivatives of the gamma
and digamma functions at their singularities}, Filomat, \textbf{27} (2013), 601-604.
