Upper and lower bounds for topological indices on unicyclic graphs
Álvaro Martínez-Pérez, José M. Rodríguez
The aim of this paper is to obtain new inequalities for a large family of topological indices restricted to unicyclic graphs and to characterize the set of extremal unicyclic graph…
New Lower Bounds for the First Variable Zagreb Index
Alvaro Martínez-Pérez, José M. Rodríguez
The aim of this paper is to obtain new sharp inequalities for a large family of topological indices, including the first variable Zagreb index , and to characterize the set…
New lower bounds for the Geometric-Arithmetic index
Alvaro Martínez-Pérez, José M. Rodríguez
The concept of geometric-arithmetic index was introduced in the chemical graph theory recently, but it has shown to be useful. The aim of this paper is to obtain new inequalities i…
Cheeger isoperimetric constant of Gromov hyperbolic manifolds and graphs
Álvaro Martínez-Pérez, José M. Rodríguez
In this paper we study the relationship of hyperbolicity and (Cheeger) isoperimetric inequality in the context of Riemannian manifolds and graphs. We characterize the hyperbolic ma…
