Berge's conjecture for cubic graphs with small colouring defect
Ján Karabáš, Edita Máčajová, Roman Nedela +1
A long-standing conjecture of Berge suggests that every bridgeless cubic graph can be expressed as a union of at most five perfect matchings. This conjecture trivially holds for $3…
The Jacobian of a graph and graph automorphisms
István Estélyi, Ján Karabáš, Alexander Mednykh +1
In the present paper we investigate the faithfulness of certain linear representations of groups of automorphisms of a graph in the group of symmetries of the Jacobian of .…
Computing equivalence classes of finite group actions on orientable surfaces: A dynamic survey
Ján Karabáš, Roman Nedela, Mária Skyvová
This paper focuses on the classification of classes of topological equivalence of finite group actions on Riemann surfaces. By the Riemann-Hurwitz bound, there are just finitely ma…
