On a generalisation of k-Dyck paths [PDF]

open access: yes, 2019
Thesis (MSc)--Stellenbosch University, 2019.ENGLISH ABSTRACT: (Refer to full text abstract for symbols that did not transfer correctly). We consider a family of non-negative lattice paths consisting of the step set f(1; 1); (1;k)g called k-Dyck paths ...

Row-Column Combination of Dyck Words

open access: yes
We lift the notion of Dyck language from words to 2-dimensional arrays of symbols, i.e., pictures. We define the Dyck crossword language as the row-column combination of Dyck word languages, which prescribes that each column and row is a Dyck word ...

Dyck paths and a bijection for multisets of hook numbers

open access: yes, 2002
We give a bijective proof of a result of Regev and Vershik (Electron J. Combin. 4 (1997) R22) on the equality of two multisets of hook numbers of certain skew–Young diagrams.

Unimodality and Dyck paths

open access: yes, 2012
We propose an original approach to the problem of rankunimodality for Dyck lattices. It is based on a well known recursive construction of Dyck paths originally developed in the context of the ECO methodology, which provides a partition of Dyck lattices into saturated chains.

Counting of subwords on restricted Dyck words

open access: yes
ilustraciones, diagramasEste trabajo se centra en el conteo de caminos de Dyck mediante el análisis de sus subpalabras. Para ello, se exploran conceptos como las funciones generatrices y sucesiones como la de Fibonacci, Lucas y Catalan.

Anchored Dyck Paths

open access: yes
We answer a question of Simental by providing a combinatorial interpretation of a formula which generalizes rational Catalan numbers and which appears in the study of Springer fibers. We provide an interpretation in terms of binary necklaces as well as anchored Dyck paths.

Counting Ascents in Generalized Dyck Paths.

open access: yes, 2018
Non-negative Lukasiewicz paths are special two-dimensional lattice paths never passing below their starting altitude which have only one single special type of down step. They are well-known and -studied combinatorial objects, in particular due to their bijective relation to trees with given node degrees.
