We construct a new bijection between the set of n × k 0–1 matrices with no three 1’s forming a ? configuration and the set of ( n, k )-Callan sequences, a simple structure counted by poly-Bernoulli numbers. We give two ...

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 ...

"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.
