Improved Lower Bounds on the General Reduced Second Zagreb Index of Trees and Unicyclic Graphs
Nasrin Dehgardi, Sandi Klavžar, Mahdieh Azari
For a simple graph and a real number , the general reduced second Zagreb index is defined by the formula A sharp lowe…
Wiener and Average Distance of Irregular Square-Cell Configuration
S. Prabhu, Sandi Klavžar, M. Anitha +2
A subgraph of the square lattice with all of its inner faces being 4-cycles is called a square-cell configuration. Prior work has provided explicit expressions for the total and av…
On -distance -packing domination number in strong products
Csilla Bujtás, Vesna Iršič Chenoweth, Sandi Klavžar +1
The -distance -packing domination number of a graph is the cardinality of a smallest set of vertices of which is both a -distance dominating set and a $…
Revisiting -distance (independent) domination in trees and in bipartite graphs
Csilla Bujtás, Vesna Iršič Chenoweth, Sandi Klavžar +1
The -distance -packing domination number of is the minimum size of a set of vertices of which is both a -distance dominating set and a -packing. In 1…
Moving through Cartesian products, coronas and joins in general position
Sandi Klavžar, Aditi Krishnakumar, Dorota Kuziak +3
The general position problem asks for large sets of vertices such that no three vertices of the set lie on a common shortest path. Recently a dynamic version of this problem was de…
Varieties of mutual-visibility and general position on Sierpiński graphs
Dhanya Roy, Sandi Klavžar, Aparna Lakshmanan +1
The variety of mutual-visibility problems contains four members, as does the variety of general position problems. The basic problem is to determine the cardinality of the largest…
