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 ...

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: Restricted r-Stirling Numbers and Their Combinatorial Applications
Szerző: ; ; ;
Dátum: 2019

We study set partitions with r distinguished elements and block sizes found in an arbitrary index set S . The enumeration of these ( S, r )-partitions leads to the introduc- tion of ( S, r )-Stirling numbers, an extremely ...
Cím: Mixed Restricted Stirling Numbers
Szerző: ; ; ;
Dátum: 2019

We investigate mixed partitions with extra condition on the sizes of the blocks. We give a general formula and the generating function. We consider in more details a special case, determining the generating functions, some ...

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: Poly-Cauchy numbers of the second kind - the combinatorics behind
Szerző: ;
Dátum: 2022
