Inherited conics in Hall planes

Aart Blokhuis, István Kovács, Gábor P. Nagy +1

The existence of ovals and hyperovals is an old question in the theory of non-Desarguesian planes. The aim of this paper is to describe when a conic of remains an a…

On k-neighbor separated permutations

István Kovács, Daniel Soltész

Two permutations of are \textit{-neighbor separated} if there are two elements that are neighbors in one of the permutations and that are separated by exa…

On groups all of whose Haar graphs are Cayley graphs

Yan-Quan Feng, Istvan Kovacs, Da-Wei Yang

A Cayley graph of a group is a finite simple graph such that contains a subgroup isomorphic to acting regularly on , while a Haar graph of is a…

Elementary abelian groups of rank 5 are DCI-groups

Yan-Quan Feng, István Kovács

In this paper, we show that the group is a DCI-group for any odd prime that is, two Cayley digraphs Cay and Cay are is…

Integral automorphisms of affine spaces over finite fields

István Kovács, Klavdija Kutnar, János Ruff +1

A permutation of the point set of the affine space is called an integral automorphism if it preserves the integral distance defined among the points. In this paper, we co…

Regular Cayley maps on dihedral groups with the smallest kernel

István Kovács, Young Soo Kwon

Let be a regular Cayley map on the dihedral group of order and let be the power function associated with . In this p…
