Lonesum and -free - fillings of Ferrers shapes
Gábor V. Nagy, Beáta Bényi
We show that -free fillings and lonesum fillings of Ferrers shapes are equinumerous by applying a previously defined bijection on matrices for this more general case and by cons…
On -poly-Bernoulli numbers arising from combinatorial interpretations
Beáta Bényi, José Luis Ramírez
In this paper we present several natural -analogues of the poly-Bernoulli numbers arising in combinatorial contexts. We also recall some relating analytical results and ask for…
A Combinatorial Analysis Of Higher Order Generalised Geometric Polynomials: A Generalisation Of Barred Preferential Arrangements
Sithembele Nkonkobe, Beáta Bényi, Roberto B. Corcino +1
A barred preferential arrangement is a preferential arrangement, onto which in-between the blocks of the preferential arrangement a number of identical bars are inserted. We offer…
Generalised Barred Preferential Arrangements
Sithembele Nkonkobe, Venkat Murali, Béata Bényi
A barred preferential arrangement is a preferential arrangement onto which a number of identical bars are inserted in between the blocks of the preferential arrangement. In this st…
Mixed coloured permutations
Beáta Bényi, Daniel Yaqubi
In this paper we introduce mixed coloured permutation, permutations with certain coloured cycles, and study the enumerative properties of these combinatorial objects. We derive the…
