Finding Identities with the WZ Method
Extending the work of Wilf and Zeilberger on WZ-pairs, we describe how new terminating hypergeometric series identities can be derived by duality from known identities. A large number of such identities are obtained by a Maple program that applies this method systematically.
متن کاملThe Markov-WZ Method
Andrei Markov’s 1890 method for convergence-acceleration of series bears an amazing resemblance to WZ theory, as was recently pointed out by M. Kondratieva and S. Sadov. But Markov did not have Gosper and Zeilberger’s algorithms, and even if he did, he wouldn’t have had a computer to run them on. Nevertheless, his beautiful ad-hoc method, when coupled with WZ theory and Gosper’s algorithm, lead...
متن کاملGenerating Function Identities for ζ(2n+2), ζ(2n+3) via the WZ Method
Using WZ-pairs we present simpler proofs of Koecher, Leshchiner and BaileyBorwein-Bradley’s identities for generating functions of the sequences {ζ(2n+2)}n≥0 and {ζ(2n + 3)}n≥0. By the same method, we give several new representations for these generating functions yielding faster convergent series for values of the Riemann zeta function.
متن کاملPfaff's method (III): Comparison with the WZ method
In the 1990's, the WZ method has been the method of choice in resolving new conjectures for hypergeometric identities. The object here is to compare the WZ method with Pfaff's method. Such a comparison should (it is hoped) provide some suggestions for the further development of each method.
متن کاملThe q-WZ method for infinite series
Abstract. Motivated by the telescoping proofs of two identities of Andrews and Warnaar, we find that infinite q-shifted factorials can be incorporated into the implementation of the q-Zeilberger algorithm in the approach of Chen, Hou and Mu to prove nonterminating basic hypergeometric series identities. This observation enables us to extend the q-WZ method to identities on infinite series. As e...
