The group is a DCI-group
István Kovács, Grigory Ryabov
We prove that the group is a DCI-group for distinct primes and , that is, two Cayley digraphs over are isomorphic if and only if their c…
Entanglement entropy of random partitioning
Gergö Roósz, István A. Kovács, Ferenc Iglói
We study the entanglement entropy of random partitions in one- and two-dimensional critical fermionic systems. In an infinite system we consider a finite, connected (hypercubic) do…
Existence of non-Cayley Haar graphs
Yan-Quan Feng, István Kovács, Jie Wang +1
A Cayley graph of a group is a finite simple graph such that its automorphism group contains a subgroup isomorphic to acting regularly on , while a…
Population boundary across an environmental gradient: Effects of quenched disorder
R. Juhász, I. A. Kovács
Population boundary is a classic indicator of climatic response in ecology. In addition to known challenges, the spatial and dynamical characteristics of the boundary are not only…
