A note on polyomino chains with extremum general sum-connectivity index

Akbar Ali, Tahir Idrees

The general sum-connectivity index of a graph $G$ is defined as ${\chi }_{\alpha }(G)={\sum }_{uv\in E(G)}(d_u+d_v{)}^{\alpha }$ where $d_u$ is degree of the vertex $u\in V(G)$, $\alpha$ is a real number…
