The rigidity of infinite graphs [PDF]

open access: yesDiscrete & Computational Geometry, 2013
A rigidity theory is developed for the Euclidean and non-Euclidean placements of countably infinite simple graphs in R^d with respect to the classical l^p norms, for d>1 and ...

Spectral partitions on infinite graphs [PDF]

open access: greenJournal of Physics A: Mathematical and General, 2000
Statistical models on infinite graphs may exhibit inhomogeneous thermodynamic behaviour at macroscopic scales. This phenomenon is of geometrical origin and may be properly described in terms of spectral partitions into subgraphs with well defined ...

Helmholtz operators on infinite graphs [PDF]

open access: yesHeliyon
The Helmholtz equation in its simplest form is Δu(a)=−k2u(a). In this note, we study a generalized discrete version of this equation on an infinite graph, by using potential-theoretic methods.

Characterizing Omega-Regularity through Finite-Memory Determinacy of Games on Infinite Graphs [PDF]

open access: yesTheoretiCS, 2023
We consider zero-sum games on infinite graphs, with objectives specified as sets of infinite words over some alphabet of colors. A well-studied class of objectives is the one of $\omega$-regular objectives, due to its relation to many natural problems in

Matchings on infinite graphs [PDF]

open access: yesProbability Theory and Related Fields, 2011
Elek and Lippner (2010) showed that the convergence of a sequence of bounded-degree graphs implies the existence of a limit for the proportion of vertices covered by a maximum matching.

Infinite matroids in graphs [PDF]

open access: yesDiscrete Mathematics, 2011
It has recently been shown that infinite matroids can be axiomatized in a way that is very similar to finite matroids and permits duality. This was previously thought impossible, since finitary infinite matroids must have non-finitary duals.

Distinguishing homomorphisms of infinite graphs [PDF]

open access: yesContributions to Discrete Mathematics, 2012
We supply an upper bound on the distinguishing chromatic number of certain infinite graphs satisfying an adjacency property. Distinguishing proper $n$-colourings are generalized to the new notion of distinguishing homomorphisms. We prove that if a graph $

On external presentations of infinite graphs [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2009
The vertices of a finite state system are usually a subset of the natural numbers. Most algorithms relative to these systems only use this fact to select vertices.

On arithmetic infinite graphs [PDF]

open access: bronzeProceedings of the Japan Academy, Series A, Mathematical Sciences, 2000
We compute explicitly the Selberg trace formula for principal congruence subgroups $\Gamma$ of $PGL(2, \mathbf{F}_q[t])$, which is the modular group in positive characteristic cases. It is known that $\Gamma \backslash X$ is an infinite Ramanujan diagram, where $X$ is the $q + 1$-regular tres.
