Sobolev Regularity of Multilinear Fractional Maximal Operators on Infinite Connected Graphs

open access: yesMathematics, 2021
Let G be an infinite connected graph. We introduce two kinds of multilinear fractional maximal operators on G. By assuming that the graph G satisfies certain geometric conditions, we establish the bounds for the above operators on the endpoint Sobolev ...

Generating Infinite Random Graphs [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 2018
AbstractWe define a growing model of random graphs. Given a sequence of non-negative integers {dn}n=0∞ with the property that di≤i, we construct a random graph on countably infinitely many vertices v0, v1… by the following process: vertex vi is connected to a subset of {v0, …, vi−1} of cardinality di chosen uniformly at random.

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.

The Dynamics of the Forest Graph Operator

open access: yesDiscussiones Mathematicae Graph Theory, 2016
In 1966, Cummins introduced the “tree graph”: the tree graph T(G) of a graph G (possibly infinite) has all its spanning trees as vertices, and distinct such trees correspond to adjacent vertices if they differ in just one edge, i.e., two spanning trees ...

Graphs whose vertex set can be partitioned into a total dominating set and an independent dominating set [PDF]

open access: yesOpuscula Mathematica
A graph \(G\) whose vertex set can be partitioned into a total dominating set and an independent dominating set is called a TI-graph. We give constructions that yield infinite families of graphs that are TI-graphs, as well as constructions that yield ...

On infinite circulant-balanced complete multipartite graphs decompositions based on generalized algorithmic approaches

open access: yesAlexandria Engineering Journal, 2022
Graph theory is a powerful and essential tool for applied scientists and engineers in analyzing and designing algorithms for several problems. Graph theory has a vital role in complex systems, especially in computer sciences. Applications of graph theory

Characterizations of the Family of All Generalized Line Graphs—Finite and Infinite—and Classification of the Family of All Graphs Whose Least Eigenvalues ≥ −2

open access: yesDiscussiones Mathematicae Graph Theory, 2013
The infimum of the least eigenvalues of all finite induced subgraphs of an infinite graph is defined to be its least eigenvalue. In [P.J. Cameron, J.M. Goethals, J.J. Seidel and E.E. Shult, Line graphs, root systems, and elliptic geometry, J. Algebra 43 (

Context-Sensitive Languages, Rational Graphs and Determinism [PDF]

open access: yesLogical Methods in Computer Science, 2006
We investigate families of infinite automata for context-sensitive languages. An infinite automaton is an infinite labeled graph with two sets of initial and final vertices.

A Framework for Rewriting Families of String Diagrams [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
We describe a mathematical framework for equational reasoning about infinite families of string diagrams which is amenable to computer automation. The framework is based on context-free families of string diagrams which we represent using context-free ...

Unicorn paths and hyperfiniteness for the mapping class group

open access: yesForum of Mathematics, Sigma, 2021
Let S be an orientable surface of finite type. Using Pho-on’s infinite unicorn paths, we prove the hyperfiniteness of orbit equivalence relations induced by the actions of the mapping class group of S on the Gromov boundaries of the arc graph and the ...
