Bijective enumerations for symmetrized poly-Bernoulli polynomials
Minoru Hirose, Toshiki Matsusaka, Ryutaro Sekigawa +1
Recently, Bényi and the second author introduced two combinatorial interpretations for symmetrized poly-Bernoulli polynomials. In the present study, we construct bijections between…

Combinatorial aspects of poly-Bernoulli polynomials and poly-Euler numbers
Beáta Bényi, Toshiki Matsusaka
In this article, we introduce combinatorial models for poly-Bernoulli polynomials and poly-Euler numbers of both kinds. As their applications, we provide combinatorial proofs of so…

On the combinatorics of symmetrized poly-Bernoulli numbers
Beáta Bényi, Toshiki Matsusaka
In this paper we introduce three combinatorial models for symmetrized poly-Bernoulli numbers. Based on our models we derive generalizations of some identities for poly-Bernoulli nu…
