El contraejemplo en la elaboración de la definición de función convexa por estudiantes universitarios
(Información tecnológica, 2019-02)
In this paper the results of an investigation that aimed to identify the role played by the counterexample in the elaboration of mathematical definitions are reported. In particular, the case of the convex function; in a ...
Hölder norm estimate for the fractal Hilbert transform in Douglis analysis
(Springer, 2017-03-21)
Douglis analysis is an alternative approach to complex methods for the investigation of linear and uniformly elliptic systems of 2n equations for 2n desired real-valued functions. The function theory associated with the ...
A Basic Backward Bifurcation Model in Epidemiology
(Applied Mathematical Sciences, 2013-06-11)
The existence of a backward bifurcation has important consequences in the strategies and control policies designed to eradicate or control an infectious disease because the policies of public health when this phenomenon ...
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.
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 ...
Bayesian analysis for a fractional population growth model
(Hindawi Publishing Corporation Journal of Applied Mathematics, 2017-01-23)
We implement the Bayesian statistical inversion theory to obtain the solution for an inverse problem of growth data, using a fractional population growth model. We estimate the parameters in the model and we make a comparison ...
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 ...
Mathematical Properties of the Hyperbolicity of Circulant Networks
(Hindawi Publishing Corporation Advances in Mathematical Physics, 2015-07-24)
The first works on Gromov hyperbolic spaces deal with finitely generated groups. Initially, Gromov spaces were applied to the study of automatic groups in the science of computation; indeed, hyperbolic groups are strongly ...
On the contextualization of mathematical problems
(International Journal of Research in Education methodology, 2015-04-03)
In this work the treatment of the cognitive interests of students is revealed, it is a way that allows the stratification of the group students according to their tastes and aspirations, and from that position by contextualizing ...
