(β)‐distortion of some infinite graphs [PDF]

open access: yesJournal of the London Mathematical Society, 2015
A distortion lower bound of Ω(log(h)1/p) is proved for embedding the complete countably branching hyperbolic tree of height h into a Banach space admitting an equivalent norm satisfying property (β) of Rolewicz with modulus of power type p∈(1,∞) (in ...

On the Metric Dimension of Infinite Graphs [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2009
A set of vertices $S$ \emph{resolves} a graph $G$ if every vertex is uniquely determined by its vector of distances to the vertices in $S$. The \emph{metric dimension} of a graph $G$ is the minimum cardinality of a resolving set. In this paper we study the metric dimension of infinite graphs such that all its vertices have finite degree.

Note on robust coloring of planar graphs [PDF]

open access: yesOpuscula Mathematica
We consider the robust chromatic number \(\chi_1(G)\) of planar graphs \(G\) and show that there exists an infinite family of planar graphs \(G\) with \(\chi_1(G) = 3\), thus solving a recent problem of Bacsó et al.

Small cancellation labellings of some infinite graphs and applications [PDF]

open access: yesActa Mathematica, 2014
We construct small cancellation labellings for some infinite sequences of finite graphs of bounded degree. We use them to define infinite graphical small cancellation presentations of groups.

Linearly bounded infinite graphs [PDF]

open access: yesActa Informatica, 2005
Linearly bounded Turing machines have been mainly studied as acceptors for context-sensitive languages. We define a natural class of infinite automata representing their observable computational behavior, called linearly bounded graphs. These automata naturally accept the same languages as the linearly bounded machines defining them. We present some of

Isospectral reduction in infinite graphs [PDF]

open access: yesJournal of Spectral Theory, 2020
L. A. Bunimovich and B. Z. Webb developed a theory for transforming a finite weighted graph while preserving its spectrum, referred as isospectral reduction theory. In this workwe extend this theory to a class of operators on Banach spaces that include Markov type operators.

Schreier graphs of the Basilica group [PDF]

open access: yes, 2010
With any self-similar action of a finitely generated group $G$ of automorphisms of a regular rooted tree $T$ can be naturally associated an infinite sequence of finite graphs $\{\Gamma_n\}_{n\geq 1}$, where $\Gamma_n$ is the Schreier graph of the action ...

Spectra of infinite graphs with tails [PDF]

open access: yes, 2015
We compute explicitly (modulo solutions of certain algebraic equations) the spectra of infinite graphs obtained by attaching one or several infinite paths to some vertices of given finite graphs.

Infinite Paley graphs

open access: yesThe Art of Discrete and Applied Mathematics, 2020
Infinite analogues of the Paley graphs are constructed, based on uncountably many infinite but locally finite fields. Weil's estimate for character sums shows that they are all isomorphic to the random or universal graph of Erd\H os, R nyi and Rado. Automorphism groups and connections with model theory are considered.

Classes of graphs with restricted interval models [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 1999
We introduce q-proper interval graphs as interval graphs with interval models in which no interval is properly contained in more than q other intervals, and also provide a forbidden induced subgraph characterization of this class of graphs.
