WebJul 1, 2024 · For example the derivative 2 F 1 ( ( 2, 0), ( 1), 0) ( { − 2, − 3 2 }, { − 1 }, x) takes a long time to evaluate and in the end produces internal variables of the HypExp2 package which do not cancel out. Mathematica 12 without the package does not even give numerical values unless x=0. WebApr 8, 2024 · Abstract Series containing the digamma function arise when calculating the parametric derivatives of the hypergeometric functions and play a role in evaluation of Feynman diagrams. As these...

WebMay 25, 2024 · Hypergeometric functions are among most important special functions mainly because they have a lot of applications in a variety of research branches such as (for example) quantum mechanics, electromagnetic field theory, probability theory, analytic number theory, and data analysis (see, e.g., [1, 2, 4–6]). Web1 Kummer's confluent hypergeometric function is: M ( a, b; z) = 1 F 1 ( a, b; z) There is an easy recurrence for the derivative of M with respect to z. I am interested in the derivative with respect to the parameters a, b. Are there any known relations involving ∂ M ∂ a, or ∂ M ∂ b? hypergeometric-function Share Cite Follow diamond holiday lettings hemsby
