Perfect state transfer and Cayley presentations
Arnbjörg Soffía Árnadóttir, Krystal Guo
We study perfect state transfer on Cayley graphs from the point of view that state transfer is a property of a graph and not of a group. This paper is a bridge between the classica…
Flow-critical graphs
Arnbjörg Soffía Árnadóttir, Zdeněk Dvořák, Bernard Lidický +3
Lovász et al. proved that every -edge-connected graph has a nowhere-zero -flow. In fact, they proved a more technical statement which says that there exists a nowhere zero $3…
Cayley Incidence Graphs
Arnbjörg Soffía Árnadóttir, Alexey Gordeev, Sabrina Lato +2
Evra, Feigon, Maurischat, and Parzanchevski (2023) introduced a biregular extension of Cayley graphs. In this paper, we reformulate their definition and provide some basic properti…
Trivalent vertex-transitive graphs with infinite vertex-stabilizers
Arnbjörg Soffía Árnadóttir, Waltraud Lederle, Rögnvaldur G. Möller
We study groups acting vertex-transitively on connected, trivalent graphs such that stabilizers of vertices are infinite. If the action is edge-transitive, we prove that the graph…
