Down-step statistics in generalized Dyck paths [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2022
The number of down-steps between pairs of up-steps in $k_t$-Dyck paths, a generalization of Dyck paths consisting of steps $\{(1, k), (1, -1)\}$ such that the path stays (weakly) above the line $y=-t$, is studied.

Pattern-avoiding Dyck paths [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
We introduce the notion of $\textit{pattern}$ in the context of lattice paths, and investigate it in the specific case of Dyck paths. Similarly to the case of permutations, the pattern-containment relation defines a poset structure on the set of all Dyck

Dyck path triangulations and extendability (extended abstract) [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
We introduce the Dyck path triangulation of the cartesian product of two simplices $\Delta_{n-1}\times\Delta_{n-1}$. The maximal simplices of this triangulation are given by Dyck paths, and its construction naturally generalizes to produce triangulations

Brauer Configuration Algebras Arising from Dyck Paths

open access: yesMathematics, 2022
The enumeration of Dyck paths is one of the most remarkable problems in Catalan combinatorics. Recently introduced categories of Dyck paths have allowed interactions between the theory of representation of algebras and cluster algebras theory. As another

Applications in Enumerative Combinatorics of In finite Weighted Automata and Graphs [PDF]

open access: yesScientific Annals of Computer Science, 2014
In this paper, we present a general methodology to solve a wide variety of classical lattice path counting problems in a uniform way. These counting problems are related to Dyck paths, Motzkin paths and some generalizations. The methodology uses weighted

Generating functions for a lattice path model introduced by Deutsch

open access: yesSpecial Matrices, 2021
The lattice path model suggested by E. Deutsch is derived from ordinary Dyck paths, but with additional down-steps of size −3, −5, −7, . . . . For such paths, we find the generating functions of them, according to length, ending at level i, both, when ...

Area of Brownian Motion with Generatingfunctionology [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
This paper gives a survey of the limit distributions of the areas of different types of random walks, namely Dyck paths, bilateral Dyck paths, meanders, and Bernoulli random walks, using the technology of generating functions only.

Rational Catalan Combinatorics: The Associahedron [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
Each positive rational number $x>0$ can be written $\textbf{uniquely}$ as $x=a/(b-a)$ for coprime positive integers ...

The location of the first maximum in the first sojourn of a Dyck path [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
For Dyck paths (nonnegative symmetric) random walks, the location of the first maximum within the first sojourn is studied. Generating functions and explicit resp. asymptotic expressions for the average are derived.
