Some results on $I ¨ _{t}$ -irregularity

Slobodan Filipovski, Darko Dimitrov, Martin Knor +1

The $I ¨ _{t}$ -irregularity (or sigma total index) is a graph invariant which is defined as $I ¨ _{t} (G) = \sum_{{u, v} \subseteq V (G)} (d (u) - d (v))^{2},$ where $d (z)$ denotes the degree o…

Extremizing antiregular graphs by modifying total $I ¨ $ -irregularity

Martin Knor, Riste Å krekovski, Slobodan Filipovski +1

The total $I ¨ $ -irregularity is given by $I ¨ _{t} (G) = \sum_{{u, v} \subseteq V (G)} (d_{G} (u) - d_{G} (v))^{2},$ where $d_{G} (z)$ indicates the degree of a vertex $z$ within the g…
