A new algorithm for the recursion of multisums with improved universal denominator
Stavros Garoufalidis, Xinyu Sun
The purpose of the paper is to introduce two new algorithms. The first one computes a linear recursion for proper hypergeometric multisums, by treating one summation variable at a…

Lattice and Schroder paths with periodic boundaries
Joseph P. S. Kung, Anna de Mier, Xinyu Sun +1
We consider paths in the plane with and -steps that start at the origin, end at height and stay to the left of a given non-decreasing right boundary.…
