Abstract

Very recently by employing two well-known Euler’s transformations for the hypergeometric function, Liu and Wang established numerous general transformation formulas for the Kampé de Fériet function and deduced many new summation formulas for the Kampé de Fériet function by using classical summation theorems for the series 2F1 due to Kummer, Gauss and Bailey. Here, we aim to establish 176 interesting summation formulas for the Kampé de Fériet function in the form of 16 general summation formulas based on the transformation formulas due to Liu and Wang. The results are derived with the help of generalizations of Kummer’s summation theorem, Gauss’ second summation theorem and Bailey’s summation theorem established earlier by Lavoie et al. The 176 formulas for the Kampé de Fériet function are pointed out to contain 16 known formulas, which are also recalled as corollaries.

Keywords: Gamma function, Pochhammer symbol, Gauss’s hypergeometric function 2F1, Generalized hypergeometric function pFq, Kampé de Fériet function, Generalization of Kummer’s summation theorem, Generalization of Gauss’ second summation theorem, Generalization of Bailey’s summation theorem
