Higher $q$-Continued Fractions

Combinatorics 2024-08-14 v1

Abstract

We introduce a qq-analog of the higher continued fractions introduced by the last three authors in a previous work (together with Gregg Musiker), which are simultaneously a generalization of the qq-rational numbers of Morier-Genoud and Ovsienko. They are defined as ratios of generating functions for PP-partitions on certain posets. We give matrix formulas for computing them, which generalize previous results in the q=1q=1 case. We also show that certain properties enjoyed by the qq-rationals are also satisfied by our higher versions.
