Cím: On the Combinatorics of Symmetrized Poly-Bernoulli Bumbers
Szerző: ;
Dátum: 2021

(2021)
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 numbers. Finally, we set open questions and ...

In this note we present a combinatorial proof of an identity involving poly-Bernoullinumbers and Genocchi numbers. We introduce combinatorial objects calledm-barredCallan sequences and use them to show that the identity ...

The relationship between precipitation and elevation is a well-known topic in the field of geography and meteorology. Radar-based precipitation data are often used in hydrologic models, however, they have several inaccuracies, ...
Cím: Laboratory experiments on the influence of stratification and a bottom sill on seiche damping

The damping of water surface standing waves (seiche modes) and the associated excitation of baroclinic internal waves are studied experimentally in a quasi-two-layer laboratory setting with a topographic obstacle at the ...
Cím: Fluid Flow Model Applied for Environmental Problems at a Combined Sewer Structure
Szerző: ; ;
Dátum: 2021

A junction structure of the greatest combined sewers of Budapest (Hungary) was under hydrodynamic and water quality examinations. The selected junction performs an important role in the operation of a combined sewer overflow. ...
Cím: Unfair distributions counted by the generalized Stirling numbers
Szerző: ; ;
Dátum: 2022
Feltöltve: 2023-02-17
(2022)
We investigate the generalized Stirling numbers S(n, k; α, β, γ) introduced by Hsu
and Shiue from a combinatorial point of view. We present a combinatorial interpretation in terms of certain restricted distributions of ...
Cím: On Higher Order Generalized Geometric Polynomials with Shifted Parameters
Szerző: ; ;
Dátum: 2022

(2022)
We study a special class of higher order generalized geometric polynomials. Based on our combinatorial interpretation of labeled barred preferential arrangements, we prove several recursions. We also study the polynomials ...
Cím: On q-Poly-Bernoulli Numbers Arising from Combinatorial Interpretations
Szerző: ;
Dátum: 2021

(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.
