Kulli-Basava Indices of Graphs
International Journal of Applied Engineering Research, 2019The mean isomer degeneracy d of a topological index decide its isomer discriminating power, the isomer discriminating power is high if d = 1 and the larger the d, the smaller is the isomer discriminating power.

Sum Geometric Harmonic Means Index of Graphs
Albaydha University Journal, 2023 In this paper, the concept of sum geometric harmonic means index of a graph G, denoted by SGhm(G) is introduced and sum geometric harmonic means index SGhm(G) of few families of graphs is computed.

Wiener index in graphs with given minimum degree and maximum degree [PDF]
Discrete Mathematics & Theoretical Computer Science, 2021 Let $G$ be a connected graph of order $n$.The Wiener index $W(G)$ of $G$ is the sum of the distances between all unordered pairs of vertices of $G$. In this paper we show that the well-known upper bound $\big( \frac{n}{\delta+1}+2\big) {n \choose 2}$ on ...

Curve graphs for Artin–Tits groups of type B, A∼ and C∼ are hyperbolic
Transactions of the London Mathematical Society, Volume 8, Issue 1, Page 151-173, December 2021., 2021 Abstract The graph of irreducible parabolic subgroups is a combinatorial object associated to an Artin–Tits group A defined so as to coincide with the curve graph of the (n+1)‐times punctured disk when A is Artin's braid group on (n+1) strands. In this case, it is a hyperbolic graph, by the celebrated Masur–Minsky's theorem.

Correlations in totally symmetric self‐complementary plane partitions
Transactions of the London Mathematical Society, Volume 8, Issue 1, Page 493-526, December 2021., 2021 Abstract Totally symmetric self‐complementary plane partitions (TSSCPPs) are boxed plane partitions with the maximum possible symmetry. We use the well‐known representation of TSSCPPs as a dimer model on a honeycomb graph enclosed in 1/12 of a hexagon with free boundary to express them as perfect matchings of a family of non‐bipartite planar graphs ...
