Injective edge coloring of generalized Petersen graphs

open access: yesAIMS Mathematics, 2021
Three edges $ e_1 $, $ e_2 $ and $ e_3 $ in a graph $ G $ are $ consecutive $ if they form a cycle of length $ 3 $ or a path in this order. A $ k $-$ injective\; edge\; coloring $ of a graph $ G $ is an edge coloring of $ G $, (not necessarily proper ...

Deterministic Distributed Edge-Coloring via Hypergraph Maximal Matching [PDF]

open access: yesIEEE Annual Symposium on Foundations of Computer Science, 2017
We present a deterministic distributed algorithm that computes a $(2\Delta-1)$-edge-coloring, or even list-edge-coloring, in any $n$-node graph with maximum degree $\Delta$, in $O(\log^7 \Delta \log n)$ rounds.

The Complexity of Distributed Edge Coloring with Small Palettes [PDF]

open access: yesACM-SIAM Symposium on Discrete Algorithms, 2018
The complexity of distributed edge coloring depends heavily on the palette size as a function of the maximum degree $\Delta$. In this paper we explore the complexity of edge coloring in the LOCAL model in different palette size regimes. 1.

Strong Edge-Coloring Of Planar Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2017
A strong edge-coloring of a graph is a proper edge-coloring where each color class induces a matching. We denote by 𝜒's(G) the strong chromatic index of G which is the smallest integer k such that G can be strongly edge-colored with k colors. It is known

Introduction to dominated edge chromatic number of a graph [PDF]

open access: yesOpuscula Mathematica, 2021
We introduce and study the dominated edge coloring of a graph. A dominated edge coloring of a graph \(G\), is a proper edge coloring of \(G\) such that each color class is dominated by at least one edge of \(G\).

Streaming Edge Coloring with Asymptotically Optimal Colors [PDF]

open access: yesInternational Colloquium on Automata, Languages and Programming, 2023
Given a graph $G$, an edge-coloring is an assignment of colors to edges of $G$ such that any two edges sharing an endpoint receive different colors. By Vizing's celebrated theorem, any graph of maximum degree $\Delta$ needs at least $\Delta$ and at most $

Low-Memory Algorithms for Online and W-Streaming Edge Coloring [PDF]

open access: yesarXiv.org, 2023
For edge coloring, the online and the W-streaming models seem somewhat orthogonal: the former needs edges to be assigned colors immediately after insertion, typically without any space restrictions, while the latter limits memory to sublinear in the ...

Distributed Edge Coloring in Time Polylogarithmic in Δ [PDF]

open access: yesACM SIGACT-SIGOPS Symposium on Principles of Distributed Computing, 2022
We provide new deterministic algorithms for the edge coloring problem, which is one of the classic and highly studied distributed local symmetry breaking problems. As our main result, we show that a (2Δ - 1)-edge coloring can be computed in time poly log

Improved Distributed Algorithms for the Lovász Local Lemma and Edge Coloring [PDF]

open access: yesACM-SIAM Symposium on Discrete Algorithms, 2022
The Lov\'asz Local Lemma is a classic result in probability theory that is often used to prove the existence of combinatorial objects via the probabilistic method.

Revisiting semistrong edge‐coloring of graphs [PDF]

open access: yesJournal of Graph Theory, 2022
A matching M $M$ in a graph G $G$ is semistrong if every edge of M $M$ has an endvertex of degree one in the subgraph induced by the vertices of M $M$ .
