Extremal chemical trees with given number of vertices of maximum degree for degree-based topological indices

Memoona Ahmad, Iqra Jahangir, Sultan Ahmad, Rashid Farooq

Published Online: 01 Apr 2026DOI: 10.47974/JDMSC-2305

In this paper: We define the general sum index for a graph G as follows: GSl,γ (G) = ∑ab∈E(G)‍ γ (dG (a)2/γ + dG (b)2/γ)l where dG(a) is the degree of a vertex a and, l and γ are non-zero real numbers. In this pape...

The Sombor index and harmonic index of chemical trees with a given number of vertices of maximum degree

Iqra Jahangir, Memoona Ahmad, Sultan Ahmad, Rashid Farooq

Published Online: 05 Feb 2026DOI: 10.47974/JDMSC-2227

In this paper: For a graph G, the Sombor index and harmonic index are respectively defined as (SO(G)=∑uv∈E(G) √(degG2 (u) + degG2 (u) and H(G) = ∑uv∈E(G) 2/(degG (u) + degG(v), where E(G) is the edge set and deg...
