Series acceleration formulas obtained from experimentally discovered hypergeometric recursions
Résumé
In 2010, Kh.\ Hessami Pilehrood and T.\ Hessami Pilehrood introduced generating function identities used to obtain series accelerations for values of Dirichlet's $\beta$ function, via the Markov--Wilf--Zeilberger method. Inspired by these past results, together with related results introduced by Chu et al., we introduce a variety of hypergeometric recurrences that we have discovered experimentally, and we prove these recurrences using the WZ method, and apply these recurrences to obtain series acceleration identities, including a family of summations generalizing a series for $\frac{1}{\pi^2}$ due to Guillera, and a family of summations generalizing an accelerated series for Catalan's constant due to Lupa\c{s}. We also provide ``non-computer'' proofs of our hypergeometric transforms.
