Cím: On q-Poly-Bernoulli Numbers Arising from Combinatorial Interpretations
Szerző: ;
Dátum: 2021
Feltöltve: 2022-09-09
(2021)
In this paper we present several natural q-analogues of the poly-Bernoulli numbers arising in combinatorial contexts. We also recall some relating analytical results and ask for combinatorial interpretations.

The chemical ecology of rotifers has been little studied. A yet unknown property is presented within some monogonant rotifers, namely the ability to produce an exogenic filamentous biopolymer, named ‘Rotimer’. This ...
Cím: Toppling on Permutations with an Extra Chip
Szerző: ;
Dátum: 2021

(2021)
The study of toppling on permutations with an extra labeled chip was initiated by the first author with D. Hathcock and P. Tetali (arXiv:2010.11236), where the extra chip was added in the middle. We extend this to all ...
Cím: On the Combinatorics of Symmetrized Poly-Bernoulli Bumbers
