چکیده
|
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 nelsen’s theorem. we consider these numbers from a probabilistic view point and demonstrate how they can be written in terms of the expectation of random descending factorial involving the negative binomial process.
