A Geometric Splitting Theorem
(2019)
Let G = G1...Gl be a connected noncompact semisimple
Lie group with Lie algebra g = g_1+g_2+....+ g_l acting topologically
transitive on a manifold M. We obtain a geometric splitting
of the metric on M that consider ...
String chopping and time-ordered products of linear string-localized quantum fields
(2018-03)
For a renormalizability proof of perturbative models in the Epstein-Glaser scheme with string-localized quantum fields, one needs to know what freedom one has in the definition of time-ordered products of the interaction ...
Geometric goodness of fit measure to detect patterns in data point clouds
(2019)
The curse of dimensionality is a commonly encountered problem in statistics and data
analysis. Variable sensitivity analysis methods are a well studied and established set of
tools designed to overcome these sorts of ...
Vertical Transmission in a Two-Strain Model of Dengue Fever
(2014)
The role of vertical transmission in vectors has rarely been addressed in the study of dengue dynamics and control, in part because it was not considered a critical population-level factor. In this paper, we apply the ...
Zilber's Dichotomy for Differentially Closed Fields with an Automorphism
(2020-07-01)
The theory of difference-differential fields of characteristic zero hasa model-companion denoted byDCFA. In [2] we prove its main properties. In[3] we proved a weak version of Zilber’s dichotomy forDCFA. In this paperwe ...
Elimination of quantifiers of a theory of real closed rings.
(2022-10-09)
Let T* be the theory of lattice-ordered subrings, without minimal (non zero) idempontents, convex in von Neumann regular real closed rings that are divisible-proyectable and sc-regular. In this paper, a local divisibility ...
On the Colmez conjecture for non-abelian CM fields
(2018-02-08)
The Colmez conjecture relates the Faltings height of an abelian variety with complex multiplication by the ring of integers of a CM field E to logarithmic derivatives of Artin L-functions at s=0. In this paper, we prove ...
Propuesta didáctica para la docencia universitaria de las ecuaciones polinomiales
Didactical proposal for teaching polynomial equations at university level
(2017)
En este artículo contiene los principales resultados obtenidos a partir del diseño, aplicación y evaluación de una propuesta didáctica para la enseñanza de las ecuaciones polinomiales, la cual se desarrolló durante el mes ...
Estimación de población contagiada por Covid-19 usando regresión Logística generalizada y heurísticas de optimización
(2020-04-02)
En este trabajos se presenta una propuesta para la estimación de la poblaciones usando ajuste de curvas del tipo logística.
Este tipo de curvas se utilizan para el estudio de crecimiento de poblaciones, en este casos ...
The Impact of Help-Seeking for Depression: A Mathematical Model
(2022)
For years and with the Covid-19 pandemic, mental illnesses such as depression have emerged. According to the World Health Organization, an average of 5\% of the population in a country suffers from depression. The ...
