摘要
Useful expressions of the derivatives, to any order, of Pochhammer and reciprocal Pochhammer symbolswith respect to their arguments are presented. They are building blocks of a procedure, recently suggested, for obtaining the e-expansion of functions of the hypergeometric class related to Feynman integrals. The procedure is applied to some examples of such kind of functions taken from the literature. (C) 2014 AIP Publishing LLC.
