Graphoidally independent infinite graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
A graphoidal cover of a graph G (not necessarily finite) is a collection ψ of paths in G, called ψ-edges, (not necessarily finite, not necessarily open) satisfying the following axioms: (GC-1) Every vertex of G is an internal vertex of at most one path ...

Ricci Curvature on Birth-Death Processes

open access: yesAxioms, 2023
In this paper, we study curvature dimension conditions on birth-death processes which correspond to linear graphs, i.e., weighted graphs supported on the infinite line or the half line. We give a combinatorial characterization of Bakry and Émery’s CD(K,n)

Spectra of infinite graphs via freeness with amalgamation [PDF]

open access: yesCanadian Journal of Mathematics - Journal Canadien de Mathematiques, 2019
We use tools from free probability to study the spectra of Hermitian operators on infinite graphs. Special attention is devoted to universal covering trees of finite graphs.

Hamilton-connectedness and Hamilton-laceability of planar geometric graphs with applications

open access: yesAIMS Mathematics, 2021
In this paper, we have used two different proof techniques to show the Hamilton-connectedness of graphs. By using the vertex connectivity and Hamiltoniancity of graphs, we construct an infinite family of Hamilton-connected convex polytope line graphs ...

Controllability of periodic bilinear quantum systems on infinite graphs [PDF]

open access: yesJournal of Mathematics and Physics, 2019
In this work, we study the controllability of the bilinear Schrodinger equation on infinite graphs for periodic quantum states. We consider the equation (BSE) $i\partial_t\psi = −\Delta \psi+ u(t)B\psi$ in the Hilbert space $L^2_p$ composed by functions ...

An Automaton Learning Approach to Solving Safety Games over Infinite Graphs [PDF]

open access: yesInternational Conference on Tools and Algorithms for Construction and Analysis of Systems, 2016
We propose a method to construct finite-state reactive controllers for systems whose interactions with their adversarial environment are modeled by infinite-duration two-player games over possibly infinite graphs.

Unfolding of Finite Concurrent Automata [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2018
We consider recognizable trace rewriting systems with level-regular contexts (RTL). A trace language is level-regular if the set of Foata normal forms of its elements is regular. We prove that the rewriting graph of a RTL is word-automatic.

A new class of graceful graphs: k-enriched fan graphs and their characterisations

open access: yesCubo, 2021
The Graceful Tree Conjecture stated by Rosa in the mid 1960s says that every tree can be gracefully labelled. It is one of the best known open problems in Graph Theory.

Geometric properties of infinite graphs and the Hardy–Littlewood maximal operator [PDF]

open access: yesJournal d'Analyse Mathematique, 2016
We study different geometric properties on infinite graphs, related to the weak-type boundedness of the Hardy–Littlewood maximal averaging operator. In particular, we analyze the connections between the doubling condition, having finite dilation and ...

Norms, kernels and eigenvalues of some infinite graphs [PDF]

open access: yesOperators and Matrices, 2018
In these paper we study the adjacency matrix of some infinite graphs, which we call the shift operator on the $L^p$ space of the graph. In particular, we establish norm estimates, we find the norm for some cases, we decide the triviality of the kernel of
