On the total k-domination in graphs
(Discussiones Mathematicae, 2018-01)
Let G = (V, E) be a graph; a set S V is a total k-domination number (G) is the minimum cardinality among all total k-dominating sets. In this paper we obtain several tight bounds for the total k-domination number of a ...
Mathematical aspects on the harmonic index
(International Journal of Mathematical Analysis, 2017-01)
The aim of this paper is to obtain new inequalities involving the harmonic index H(G) to other well-known topological indices. Moreover, we show that the computation of the harmonic index is reduced to the computation of ...

The hyperbolicity constant of infinite circulant graphs
(Open Mathematics, 2017-03-30)
The space X is hyperbolic.in the Gromov sense/ if any side of T is contained in a neighborhood of the union of the two other sides, for every geodesic triangle T in X. Deciding whether or not a graph is hyperbolic is usually ...
Approximation to the study of water quality
(Applied Mathematical Sciences, 2018-03-25)
The main objective of this study is to propose a discrete approach to water quality study, applied to freshwater ecosystems, through the uctuations in the populations of benthic macroinvertebrates and their tolerance to pollution.
Spectral study of the Geometric-Arithmetic Index
(Communications in Mathematical and in Computer Chemistry, 2015-11-14)
The concept of geometric-arithmetic index was introduced in the chemical graph theory recently, but it has shown to be useful. One of the main aims of algebraic graph theory is to determine how, or whether, properties of ...
Stochastic black-scholes equation with time-fractional derivative on the half-line
(International Journal of Pure and Applied Mathematics, 2016-01)
We investigate the pricing of options using a modified Black-Scholes equation with a time-fractional derivative and additive white noise on the half-line. We construct the Green function for the initial-boundary value ...
Modelo logístico de orden fraccionario: Un análisis Bayesiano
(Universidad Autónoma de Guerrero (México), 2017-01)
Among the objectives of Mathematics is to try to describe and predict events that happen in the real world; this is essentially achieved through mathematical representations. Many of the laws of nature can be studied through ...
