Abstract

In 2019, Mathur and Solanki \cite{7,8} obtained a few transformation formulas for Appell, Horn and the Kamp\'{e} de F\'{e}riet functions. Unfortunately, some of the results are well-known and very old results in literature while others are erroneous. Thus the aim of this note is to provide the results in corrected forms and some of the results have been written in more compact form.

Keywords: Hypergeometric function, Kummer's second theorem, contiguous results, Appell's series, Horn's function, Kamp\'{e} de F\'{e}riet function
