New modular symmetric function and its applications: Modular -Stirling numbers
Bazeniar Abdelghafour, Moussa Ahmia, José L. Ramírez +1
In this paper, we consider a generalization of the Stirling number sequence of both kinds by using a specialization of a new family of symmetric functions. We give combinatorial in…
Restricted Dyck Paths on Valleys Sequence
Rigoberto Flórez, Toufik Mansour, José L. Ramírez +2
In this paper we study a subfamily of a classic lattice path, the \emph{Dyck paths}, called \emph{restricted -Dyck} paths, in short -Dyck. A valley of a Dyck path is a lo…
Poly-Cauchy numbers -- the combinatorics behind
Beáta Bényi, José Luis Ramírez
We introduce poly-Cauchy permutations that are enumerated by the poly-Cauchy numbers. We provide combinatorial proofs for several identities involving poly-Cauchy numbers and some…
Palindromic and Colored Superdiagonal Compositions
Jazmín Mantilla, Wilson Olaya-León, José L. Ramírez
A superdiagonal composition is one in which the -th part or summand is of size greater than or equal to . In this paper, we study the number of palindromic superdiagonal comp…
