Breaking small automorphisms of graphs of arbitrary cardinality
Marcin Stawiski
We say that an edge colouring of a graph preserves an automorphism if maps each edge to an edge of the same colour. Otherwise, we say that breaks . We call an…
Irreducible distinguishing colourings and the Axiom of Choice
Marcin Stawiski
We say that a vertex or edge colouring of a graph is distinguishing if the only automorphism that preserves this colouring is the identity. A (proper) distinguishing colouring is i…
A new problem related to Eulerian graphs
Marcin Stawiski
Let be a graph, and be a finite subgraph of . We say that is a (semi) -Eulerian subgraph if there exists a closed (open) trail in such that each edge of $…
Distinguishing finite and infinite trees of arbitrary cardinality
Wilfried Imrich, RafaÅ Kalinowski, Florian Lehner +2
Let be a finite or infinite graph and the minimum number of vertices moved by the non-identity automorphisms of . We are interested in bounds on the supremum …
Distinguishing regular graphs from lists
Jakub KwaÅny, Marcin Stawiski
An edge colouring of a graph is called distinguishing if there is no non-trivial automorphism which preserves it. We prove that every at most countable, finite or infinite, connect…
