The local vertex anti-magic coloring for certain graph operations [PDF]

open access: yesHeliyon
This work proves the local vertex anti-magic coloring of even regular circulant bipartite graphs C(m;L). Let G be either Kr,r or Kr,r−F, F is a 1-factor.

Note on group distance magic complete bipartite graphs [PDF]

open access: yesOpen Mathematics, 2014
A Γ-distance magic labeling of a graph G = (V, E) with |V| = n is a bijection ℓ from V to an Abelian group Γ of order n such that the weight $$w(x) = \sum\nolimits_{y \in N_G (x)} {\ell (y)}$$ of every vertex x ∈ V is equal to the same element µ ∈ Γ ...

Spectral extrema of graphs with fixed size: Cycles and complete bipartite graphs [PDF]

open access: yesEuropean journal of combinatorics (Print), 2021
Nikiforov (2002) showed that if G is K r + 1 -free then the spectral radius ρ ( G ) ≤ 2 m ( 1 − 1 ∕ r ) , which implies that G contains C 3 if ρ ( G ) > m .

Packing Colourings in Complete Bipartite Graphs and the Inverse Problem for Correspondence Packing [PDF]

open access: yesJournal of Graph Theory, 2023
Applications of graph colouring often involve taking restrictions into account, and it is desirable to have multiple (disjoint) solutions. In the optimal case, where there is a partition into disjoint colourings, we speak of a packing.

Cutoff for the averaging process on the hypercube and complete bipartite graphs [PDF]

open access: yesElectronic Journal of Probability, 2022
We consider the averaging process on a graph, that is the evolution of a mass distribution undergoing repeated averages along the edges of the graph at the arrival times of independent Poisson processes.

P_4-Colorings and P_4-Bipartite Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2001
A vertex partition of a graph into disjoint subsets V_is is said to be a P_4-free coloring if each color class V_i induces a subgraph without chordless path on four vertices (denoted by P_4).

A Note on the Equitable Choosability of Complete Bipartite Graphs [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2018
In 2003 Kostochka, Pelsmajer, and West introduced a list analogue of equitable coloring called equitable choosability. A k-assignment, L, for a graph G assigns a list, L(v), of k available colors to each v ∈ V (G), and an equitable L-coloring of G is a ...
