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 ...

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 ...

In the paper, the authors present several new relations and applications for the combinatorialsequence that counts the possible partitions of a finite set with the restriction that the size ofeach block is contained in a ...

"Lonesum matrices are matrices that are uniquely reconstructible from their row and column sum vectors. These matrices are enumerated by the poly-Bernoulli numbers"," a sequence related to the multiple zeta values with a ...

In this note we prove, using combinatorial arguments, some new formulas connecting Poly-Bernoulli numbers with negative indices to Eulerian numbers.
Cím: Poly-Cauchy numbers of the second kind - the combinatorics behind

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 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: On q-Poly-Bernoulli Numbers Arising from Combinatorial Interpretations

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.
