Corner contribution to cluster numbers in the Potts model
István A. Kovács, Eren Metin Elçi, Martin Weigel +1
For the two-dimensional Q-state Potts model at criticality, we consider Fortuin-Kasteleyn and spin clusters and study the average number N_Gamma of clusters that intersect a given…
On schurity of finite abelian groups
Sergei Evdokimov, István Kovács, Ilya Ponomarenko
A finite group is called a Schur group, if any Schur ring over is associated in a natural way with a subgroup of that contains all right translations. Recently, th…
A classification of nilpotent 3-BCI groups
Hiroki Koike, István Kovács
Given a finite group and a subset the bi-Cayley graph $\bcay(G,S)$ is the graph whose vertex set is and edge set is $\{\{(x,0),(s x,1)\} : x…
Cubic symmetric graphs having an abelian automorphism group with two orbits
Hiroki Koike, István Kovács
Finite connected cubic symmetric graphs of girth 6 have been classified by K. Kutnar and D. Marušič, in particular, each of these graphs has an abelian automorphism group with two…
The number of cyclic configurations of type and the isomorphism problem
Sergio Hiroki Koike-Quintanar, István Kovács, Tomaž Pisanski
A configuration of points and lines is cyclic if it has an automorphism which permutes its points in a full cycle. A closed formula is derived for the number of non-isomorphic conn…
