We introduce a -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 -rational numbers of Morier-Genoud and Ovsienko. They are defined as ratios of generating functions for -partitions on certain posets. We give matrix formulas for computing them, which generalize previous results in the case. We also show that certain properties enjoyed by the -rationals are also satisfied by our higher versions.
期刊介绍:
The European Journal of Combinatorics is a high standard, international, bimonthly journal of pure mathematics, specializing in theories arising from combinatorial problems. The journal is primarily open to papers dealing with mathematical structures within combinatorics and/or establishing direct links between combinatorics and other branches of mathematics and the theories of computing. The journal includes full-length research papers on important topics.
