Computing the Hamiltonian compression factors of cubic graphs

Marston Conder, Gregor Potocnik, Primoz Potocnik

We present an algorithm for computing Hamiltonian cycles that are invariant under a graph automorphism acting on them as a rotation. We also present an application of this algorith…

Separating subsets from their images

Marco Barbieri, Maruša Lekše, Primož Potočnik +1

Let be a transitive permutation group acting on . In this paper, we introduce and study the parameter , which denotes the size of the smallest set of points …

An infinite family of simple graphs underlying chiral, orientable reflexible and non-orientable rotary maps

Isabel Hubard, Primož Potočnik, Primož Šparl

In this paper, we provide the first known infinite family of simple graphs, each of which is the skeleton of a chiral map, a skeleton of a reflexible map on an orientable surfaces,…

Nut digraphs

Nino Bašić, Patrick W. Fowler, Maxine M. McCarthy +1

A nut graph is a simple graph whose kernel is spanned by a single full vector (i.e. the adjacency matrix has a single zero eigenvalue and all non-zero kernel eigenvectors have no z…

Vertex-transitive graphs with small motion and transitive permutation groups with small minimal degree

Antonio Montero, Primož Potočnik

The motion of a graph is the minimum number of vertices that are moved by a non-trivial automorphism. Equivalently, it can be defined as the minimal degree of its automorphism grou…

Vertex-primitive digraphs with large fixity

Marco Barbieri, Primož Potočnik

The relative fixity of a digraph is defined as the ratio between the largest number of vertices fixed by a nontrivial automorphism of and the number of vertices of . We…
