Path and cycle decompositions of dense graphs

A Girão, B Granet, D Kühn… - Journal of the London …, 2021 - Wiley Online Library
We make progress on three long standing conjectures from the 1960s about path and cycle
decompositions of graphs. Gallai conjectured that any connected graph on n vertices can be …

Path decompositions of random directed graphs

AE Díaz, V Patel, F Stroh - arXiv preprint arXiv:2109.13565, 2021 - arxiv.org
We consider the problem of decomposing the edges of a directed graph into as few paths as
possible. There is a natural lower bound for the number of paths needed in an edge …

Path decompositions of oriented graphs

V Patel, MA Yıldız - arXiv preprint arXiv:2411.06982, 2024 - arxiv.org
We consider the problem of decomposing the edges of a digraph into as few paths as
possible. A natural lower bound for the number of paths in any path decomposition of a …

Long directed paths in Eulerian digraphs

O Janzer, B Sudakov, I Tomon - arXiv preprint arXiv:2101.11601, 2021 - arxiv.org
An old conjecture of Bollob\'as and Scott asserts that every Eulerian directed graph with
average degree $ d $ contains a directed cycle of length at least $\Omega (d) $. The best …

Path and cycle decompositions of graphs and digraphs

B Granet - 2022 - etheses.bham.ac.uk
In this thesis, we make progress on five long standing conjectures on path and cycle
decompositions of graphs and digraphs. Firstly, we confirm a conjecture of Jackson from …

Path decompositions of random directed graphs

A Espuny Díaz, V Patel, F Stroh - Extended Abstracts EuroComb 2021 …, 2021 - Springer
In this work we consider extensions of a conjecture due to Alspach, Mason, and Pullman
from 1976. This conjecture concerns edge decompositions of tournaments into as few paths …

Note on long paths in eulerian digraphs

C Knierim, M Larcher, A Martinsson - arXiv preprint arXiv:2103.05330, 2021 - arxiv.org
Long Paths and Cycles in eulerian digraphs have gotten a lot of attention recently. In this
short note, we show how to use methods from Knierim, Larcher, Martinsson, Noever (2021) …

[PDF][PDF] On Partition Problems in Combinatorics

C Knierim - 2022 - research-collection.ethz.ch
This thesis shines light on two very important topics in combinatorics: Ramsey theory and
graph decomposition problems. Studied since the beginning of the 20th century, Ramsey …

[PDF][PDF] Hamilton cycles and algorithms

F Stroh - 2022 - pure.uva.nl
This thesis is concerned with the mathematical field of graph theory. Graphs can be used to
model many different situations or represent different types of networks (eg transport …
