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 ...
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 ...
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 ...
Generating Function: Multiple Orthogonal Polynomials
(Applied Mathematical Sciences, 2016-03-09)
At present, interest in the study of multiple orthogonal polynomials has increased due to the development of simultaneous rational approximation of functions and the link between the two theories. Orthogonal polynomials ...
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 ...
Fractional stochastic heat equation on the Half-Line
(Applied Mathematical Sciences, 2016-11-12)
In this paper, we consider an initial-boundary value problem for a stochastic non-linear heat equation with Riemann-Liouville spacefractional derivative and white noise on the half-line. We construct the integral representation ...
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 ...
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 ...
