Dihedral groups of square-free order are DCI-groups

István Kovács, Gábor Somlai

A finite group $G$ is a called a DCI-group if any two isomorphic Cayley digraphs of $G$ are also isomorphic via an automorphism of $G$ . If $G$ is a non-abelian generalised dihedral…

Activity propagation with Hebbian learning

Will T. Engedal, Róbert Juhász, István A. Kovács

We investigate the impact of Hebbian learning on the contact process, a paradigmatic model for infection spreading, which has been also proposed as a simple model to capture the dy…

Universal shape-dependence of quantum entanglement in disordered magnets

Natalie Love, István A. Kovács

Disordered quantum magnets are not only experimentally relevant, but offer efficient computational methodologies to calculate the low energy states as well as various measures of q…

Cyclic $m$ -DCI-groups and $m$ -CI-groups

István Kovács, Luka Šinkovec

Based on the earlier work of Li (European J. Combin. 1997) and Dobson (Discrete Math. 2008), in this paper we complete the classification of cyclic $m$ -DCI-groups and $m$ -CI-groups…
