In the first two sections of the paper, stream flow is investigated on a probability theoretical basis. We will show that under some realistic conditions its probability distribution is of gamma type. In the model of the ...

In this note we prove, using combinatorial arguments, some new formulas connecting Poly-Bernoulli numbers with negative indices to Eulerian numbers.
Cím: Unfair distributions counted by the generalized Stirling numbers

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: Weak Ascent Sequences and Related Combinatorial Structures

In this paper we introduce weak ascent sequences, a class of number sequences that properly contains ascent sequences. We show how these sequences uniquely encode each of the following objects: permutations avoiding a ...
Cím: Mammal Extinction Facilitated Biome Shift and Human Population Change During the Last Glacial Termination in East-Central Europe

"The study of local extinction times, together with the associated environmental and human population changes in the last glacial termination, provides insights into the causes of mega- and microfauna extinctions. In ...
Cím: A Bijection for the Boolean Numbers of Ferrers Graphs

Dátum: 2022

(Springer Japan, 2022)
In this note we prove a new characterization of the derangement sets of Ferrers graphs and present a bijection between the derangement sets and Fλ-Callan sequences. In particular, this connection reveals that the boolean ...
Cím: Generalized barred preferential arrangements
Szerző: ; ; ;
Dátum: 2023

We investigate a generalization of Fubini numbers. We present the combinatorial interpretation as barred preferential arrangements with some additional conditions on the blocks. We provide a proof for a generalization of ...
Cím: Poly-Cauchy numbers of the second kind - the combinatorics behind
Szerző: ;
Dátum: 2022

(2022)
We introduce poly-Cauchy permutations of the second kind that are enumerated by the polyCauchy numbers of the second kind. We provide combinatorial proofs for several identities involving polyCauchy numbers of the second ...

We introduce probabilistic Stirling numbers of the first kind s_Y(n,k) s Y ( n , k ) associated with a complex-valued random variable Y satisfying appropriate integrability conditions, thus completing the notion of ...
