An extension of the method of brackets. Part 1 [PDF]

open access: yesOpen Mathematics, 2017
The method of brackets is an efficient method for the evaluation of alarge class of definite integrals on the half-line. It is based on a small collection of rules, some of which are heuristic.

A Fast Approach to Creative Telescoping [PDF]

open access: yes, 2010
In this note we reinvestigate the task of computing creative telescoping relations in differential-difference operator algebras. Our approach is based on an ansatz that explicitly includes the denominators of the delta parts.

Approximations to -, di- and tri- logarithms [PDF]

open access: yes, 2004
We propose hypergeometric constructions of simultaneous approximations to polylogarithms. These approximations suit for computing the values of polylogarithms and satisfy 4-term Apery-like (polynomial) recursions.Comment: 11 pages, minor ...

The q-WZ Method for Infinite Series [PDF]

open access: yes, 2008
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

New conservation laws and exact solutions of the special case of the fifth-order KdV equation

open access: yesJournal of Ocean Engineering and Science, 2022
The current study deals with the Kaup-Kupershmidt (KK) equation to construct formal Lagrangian, conservation laws, and exact solutions. KK is basically a special case of the 5th-order KdV equation. The conservation laws obtained by using the conservation

Applicability of the $q$-Analogue of Zeilberger's Algorithm [PDF]

open access: yes, 2004
The applicability or terminating condition for the ordinary case of Zeilberger's algorithm was recently obtained by Abramov. For the $q$-analogue, the question of whether a bivariate $q$-hypergeometric term has a $qZ$-pair remains open.
