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.
-Stirling numbers associated to potential polynomials
José A. Adell, Beáta Bényi
We introduce the -Stirling numbers of the first and second kind, which are the coefficients of the potential polynomials when we express them in terms of the monomials and the f…
Pattern Avoidance in Weak Ascent Sequences
Beáta Bényi, Toufik Mansour, José L. Ramírez
In this paper, we study pattern avoidance in weak ascent sequences, giving some results for patterns of length 3. This is an analogous study to one given by Duncan and Steingrímsso…
Mixed restricted Stirling numbers
Somaya Barati, Beáta Bényi, Abbas Jafarzadeh +1
In this note we investigate mixed partitions with extra condition on the sizes of the blocks. We give a general formula and the generating function. We consider in more details a s…
