Derivatives of Horn's hypergeometric functions G1, G2, Γ1, and Γ2 with respect to their parameters

We establish the nth-order derivatives of Horn hypergeometric functions G1, G2, Γ1, and Γ2 with respect to the parameters. We discuss applications to the calculation of recursion formulas and contiguous relations. © 2023 Elsevier Inc. All rights reserved.
