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 ...
Klebsiella variicola and Klebsiella quasipneumoniae genomic analysis provides insights into their capacity to adapt to clinical and plant settings
(Salud Pública de México, 2017-02-24)
Objective. To compare the genetic determinants involved in plant colonization or virulence in the reported genomes of K. variicola, K. quasipneumoniae and K. pneumoniae. Materials and methods. In silico comparisons and ...
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 ...
Methodology based on problem solving in the treatment of the concept of limit to infinity
(International Journal of Research in Education Methodology, 2014-01)
In this research, a methodological strategy it is raised for the assimilation of the concept of infinity limit in the teaching and learning of calculus at the University level. The strategy considers the contributions and ...
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 ...
Changes in structure and diversity of woody plants in a secondary mixed Pine-Oak forest in the sierra madre del Sur of Mexico
(Forests, 2016-04-22)
The biotic province of the Sierra Madre del Sur presents a mosaic of woodlands at different successional stages due to frequent modifications in land use. In this study, we analyzed changes in woody flora across three ...
Avifauna de los pueblos santos de la sierra madre del sur de guerrero: análisis de la riqueza y recambio taxonómico entre tipos de vegetación
(Acta zoológica Mexicana, 2018-04)
The Sierra Madre del Sur is a region biologically important for its high levels of richness and endemism. In the last two decades, the pressure on their natural resources has increased, which threatens its biodiversity. ...
