Efficient and high-performance routing of lattice-surgery paths on three-dimensional lattice [PDF]

open access: yesQuantum
Encoding logical qubits with surface codes and performing multi-qubit logical operations with lattice surgery is one of the most promising approaches to demonstrate fault-tolerant quantum computing.

Distinct Lattice Paths

open access: yes, 2022
Lattice paths can be used to model scheduling and routing problems, and, therefore, identifying maximum sets of distinct paths is of general interest. We extend the work previously done by Gillman et al.

The Carlitz lattice path polynomials

open access: yesDiscrete Mathematics, 2000
The author interprets some polynomials of Carlitz as generating functions for some natural statistics on lattice paths in \(\mathbb{R}^n\) \((n= 2,3)\) which admit diagonal moves.

Split lattice paths and Rogers-Ramanujan type identities: Split lattice paths and RR type identities

open access: yes
In this paper, an open problem posed by the second author [On $q$-series and split lattice paths, Graphs and Combinatorics, 2020] is addressed. Here, we provide combinatorial interpretations of four generalized basic series in terms of split lattice ...

Lattice Paths Between Diagonal Boundaries [PDF]

open access: yesThe Electronic Journal of Combinatorics, 1998
A bivariate symmetric backwards recursion is of the form $d[m,n]=w_{0}(d[m-1,n]+d[m,n-1])+\omega_{1}(d[m-r_{1},n-s_{1}]+d[m-s_{1},n-r_{1}])+\dots+\omega_{k}(d[m-r_{k},n-s_{k}]+d[m-s_{k},n-r_{k}])$ where $\omega_{0},\dots\omega_{k}$ are weights, $r_{1},\dots r_{k}$ and $s_{1},\dots s_{k}$ are positive integers.

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

Generalized Schröder matrices arising from enumeration of lattice paths [PDF]

open access: yes, 2020
summary:We introduce a new family of generalized Schröder matrices from the Riordan arrays which are obtained by counting of the weighted lattice paths with steps $E = (1, 0)$, $ D = (1,1)$, $ N= (0,1)$, and $ D' = (1,2)$ and not going above the line $y ...

Nonintersecting lattice paths on the cylinder

open access: yesSeminaire Lotharingien de Combinatoire, 2003
We show how a formula concerning ``vicious walkers'' (which basically are nonintersecting lattice paths) on the cylinder given by P.J. Forrester can be proved and generalized by using the Lindström--Gessel--Viennot method, after having things set up in the right way.

On the h-Vector of a Lattice Path Matroid [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2010
Stanley has conjectured that the h-vector of a matroid complex is a pure M-vector. We prove a strengthening of this conjecture for lattice path matroids by constructing a corresponding family of discrete polymatroids.
