Abstract
The content delves into the investigation of Appell F1, F3, Lauricella F (3) D, and Lauricella-Saran F (3) S series. These functions are crucial in mathematical physics, especially in evaluating Feynman integrals. The study aims to provide comprehensive analytic continuations and practical packages for efficient numerical evaluations. Various strategies are employed to enhance the accuracy and efficiency of computations, including selecting suitable analytic continuations and optimizing summation techniques. The article also discusses the method of Olsson for deriving these analytic continuations and presents detailed algorithms for implementing these functions in Mathematica.
