Analytic continuations of the Horn $H_{1}$ and $H_{5}$ functions

Souvik Bera, Tanay Pathak

The analytic continuations (ACs) of the double variable Horn $H_{1}$ and $H_{5}$ functions have been derived for the first time using the automated symbolic $Mathematica$ pack…

$ε$ -Expansion of Multivariable Hypergeometric Functions Appearing in Feynman Integral Calculus

Souvik Bera

We present a new methodology, suitable for implementation on computer, to perform the $ε$ -expansion of hypergeometric functions with linear $ε$ dependent Pochhammer parameters in a…
