Resolving vertices of graphs with differences
Iztok Peterina, Jelena Sedlar, Riste Škrekovski +1
The classical (vertex) metric dimension of a graph G is defined as the cardinality of a smallest set S in V (G) such that any two vertices x and y from G have different distances t…
Normal 5-edge-coloring of some snarks superpositioned by the Petersen graph
Jelena Sedlar, Riste Škrekovski
In a (proper) edge-coloring of a bridgeless cubic graph G an edge e is rich (resp. poor) if the number of colors of all edges incident to end-vertices of e is 5 (resp. 3). An edge-…
Selected topics on Wiener index
Martin Knor, Riste Škrekovski, Aleksandra Tepeh
The Wiener index is defined as the sum of distances between all unordered pairs of vertices in a graph. It is one of the most recognized and well-researched topological indices, wh…
Local Irregularity Conjecture vs. cacti
Jelena Sedlar, Riste Škrekovski
A graph is locally irregular if the degrees of the end-vertices of every edge are distinct. An edge coloring of a graph G is locally irregular if every color induces a locally irre…
A note on the locally irregular edge colorings of cacti
Jelena Sedlar, Riste Škrekovski
A graph is locally irregular if the degrees of the end-vertices of every edge are distinct. An edge coloring of a graph G is locally irregular if every color induces a locally irre…
On the minimum value of sum-Balaban index
Martin Knor, Jaka Kranjc, Riste Škrekovski +1
We consider extremal values of sum-Balaban index among graphs on vertices. We determine that the upper bound for the minimum value of the sum-Balaban index is at most …
