چکیده
|
for any graph g, the modified sombor index is defined as the reciprocal of the well-known sombor index. the girth of g, by short g(g), is the length of the smallest cycle in g. a graph with exactly one cycle is a unicyclic graph. if it is further, connected, it is a connected unicyclic graph. in this article, we achieved the modified sombor index for a collection of graphs, connected unicyclic graphs and also obtained the maximum modified sombor index for the class of unicyclic graphs based on the restrictions by a fixed girth.
