On singular signed graphs with nullspace spanned by a full vector: Signed nut graphs
Nino Bašić, Patrick W. Fowler, Tomaž Pisanski +1
A signed graph has edge weights drawn from the set , and is termed sign-balanced if it is equivalent to an unsigned graph under the operation of sign switching; otherwis…
Regular Antilattices
Karin Cvetko-Vah, Michael Kinyon, Jonathan Leech +1
Antilattices for which the Green's equivalences , , and are all congruence…
The Sierpiński product of graphs
Jurij Kovič, Tomaž Pisanski, Sara Sabrina Zemljič +1
In this paper we introduce a product-like operation that generalizes the construction of generalized Sierpiński graphs. Let be graphs and let be a function…
Point-ellipse and some other exotic configurations
Gábor Gévay, Nino Bašić, Jurij Kovič +1
In this paper we introduce point-ellipse configurations and point-conic configurations. We study some of their basic properties and describe two interesting families of balanced po…
Characterization of generalized Petersen graphs that are Kronecker covers
Matjaž Krnc, Tomaž Pisanski
The family of generalized Petersen graphs , introduced by Coxeter et al. [4] and named by Mark Watkins (1969), is a family of cubic graphs formed by connecting the vertice…
Vertex-transitive Haar graphs that are not Cayley graphs
Marston Conder, István Estélyi, Tomaž Pisanski
In a recent paper (arXiv:1505.01475 ) Estélyi and Pisanski raised a question whether there exist vertex-transitive Haar graphs that are not Cayley graphs. In this note we construct…
