[HTML][HTML] Breaking graph symmetries by edge colourings

F Lehner - Journal of Combinatorial Theory, Series B, 2017 - Elsevier
The distinguishing index D′(G) of a graph G is the least number of colours needed in an
edge colouring which is not preserved by any non-trivial automorphism. Broere and Pilśniak …

Bounds for distinguishing invariants of infinite graphs

W Imrich, R Kalinowski, M Pilśniak… - arXiv preprint arXiv …, 2019 - arxiv.org
We consider infinite graphs. The distinguishing number $ D (G) $ of a graph $ G $ is the
minimum number of colours in a vertex colouring of $ G $ that is preserved only by the trivial …

Distinguishing infinite graphs with bounded degrees

F Lehner, M Pilśniak, M Stawiski - Journal of Graph Theory, 2022 - Wiley Online Library
Call a colouring of a graph distinguishing if the only colour preserving automorphism is the
identity. A conjecture of Tucker states that if every automorphism of a connected graph GG …

Coarse distinguishability of graphs with symmetric growth

JAÁ López, RB Lijó, H Nozawa - arXiv preprint arXiv:2005.09716, 2020 - arxiv.org
Let $ X $ be a connected, locally finite graph with symmetric growth. We prove that there is a
vertex coloring $\phi\colon X\to\{0, 1\} $ and some $ R\in\mathbb {N} $ such that every …
