Combinatorics of higher order degenerate -DERANGED Bell Numbers

Sithembele Nkonkobe

When one inserts a number of identical bars in between blocks of an ordered set partition, they obtain a barred preferential arrangement. In this study we define a new generalizati…

Partial degenerate Stirling numbers

Beáta Bényi, Sithembele Nkonkobe

In this paper, we study some combinations of the degenerate and incomplete Stirling numbers of the second kind. We use a combinatorial approach and provide some asymptotic results.
