Bounds on Harary index

Journal of Mathematical Chemistry, 2009
In this paper, we obtain the lower and upper bounds on the Harary index of a connected graph (molecular graph), and, in particular, of a triangle- and quadrangle-free graphs in terms of the number of vertices, the number of edges and the diameter.

Bounds for the Randić Connectivity Index

Journal of Chemical Information and Computer Sciences, 1999
For a saturated hydrocarbon with n carbon atoms and m carbon-carbon bonds and with Randic connectivity index chi, two functions, L = L(n,m) and U = U(n,m), are determined, such that L < or = chi < U. These bounds are better than those previously reported; for most chemically relevant values of n and m there exist hydrocarbons for which chi = L or chi =

GEOMETRIC BOUNDS ON THE RELATIVE INDEX

Journal of the Institute of Mathematics of Jussieu, 2002
The author introduces the notion of the relative index for a pair of embeddable CR structures. Let \((Y,{\xi})\) be a contact 3-manifold with the contact structure \(\xi\). Let \(J,J^{\prime}\) denote a pair of embeddable CR structures on \(Y\), compatible with \(\xi\).

Special Jordan nil algebras of bounded index

Algebra and Logic, 1983
The Nagata-Higman theorem states that an associative nil-algebra of bounded index n, without elements of additive order \(\leq n\), is nilpotent. An example due to \textit{G. V. Dorofeev} [Usp. Mat. Nauk 15, No.3(93), 147-150 (1960; Zbl 0095.023)] shows this theorem cannot be fully extended to Jordan algebras.

Atom-Bond Connectivity Index and Arithmetic-Geometric Index: Bounding Relationships

International Journal of Mathematics and Computer Science
In this paper, we establish extremal results and bounds of the atom-bond connectivity index with the arithmetic-geometric index given the minimum and maximum degrees of a graph. We have shown that regular graphs correspond to extremal graphs.

Bounding Robustness via Kirchhoff Index

2017
Bounding robustness in complex networks has gained increasing attention in the literature. Network robustness research has indeed been carried out by scientists with different backgrounds, like mathematics, physics, computer science and biology. As a result, quite a lot of different approaches to capture the robustness properties of a network have been
