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 ...
Los grupos simplécticos y su representación en la teoría del producto cuántico. I. Sp(2,R)
(1987)
El álgebra de observables de la teoría cuántica encierra una
representación del grupo simpléctico. Esta puede usarse a su vez para
resolver problemas de caracterización de estados y síntesis espectral
en la formulación ...
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 ...
A numerical implementation for the high-order 2D Virtual Element Method in MATLAB
(2021)
We present a numerical implementation for the Virtual Element Method that in-
corporates high order spaces. We include all the required computations in order to assemble the
stiffness and mass matrices, and right hand ...
A posteriori error analysis for a viscous flow-transport problem
(2016)
In this paper we develop an a posteriori error analysis for an augmented mixed-primal finite element approximation of a stationary viscous flow and transport problem. The governing system corresponds to a scalar, nonlinear ...
S-matrix from the metaplectic representation
(1992-03)
We show how the S-matrix for bosons in an external field can be derived directly from the infinite dimensional metaplectic representation, in terms of the classical scattering operator.
Models of torsors and the fundamental group scheme
(2018)
Given a relative faithfully
at pointed scheme over the spectrum
of a discrete valuation ring X !S, this paper is motivated by the study of
the natural morphism from the fundamental group scheme of the generic ber
X ...
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 ...
New mixed finite element methods for natural convection with phase-change in porous media
(2019)
This article is concerned with the mathematical and numerical analysis of a steady phase change problem for non-isothermal incompressible viscous flow. The system is formulated in terms of pseudostress, strain rate and ...
A posteriori error analysis of mixed finite element methods for stress-assisted diffusion problems
(2022)
We develop the a posteriori error analysis for mixed-primal and fully-mixed finite element methods approximating the stress-assisted diffusion of solutes in elastic materials. The systems are formulated in terms of stress, ...
