Stora's fine notion of divergent amplitudes
(2016-11)Stora and coworkers refined the notion of divergent quantum amplitude, somewhat upsetting the standard power-counting recipe. This unexpectedly clears the way to new prototypes for free and interacting field theories of ... -
Stratifications on the Moduli Space of Higgs Bundles
(2016-11-02)The moduli space of Higgs bundles has two stratifications. The Bia lynickiBirula stratification comes from the action of the non-zero complex numbers by multiplication on the Higgs field, and the Shatz stratification arises ... -
Teoría de grupos en cuantización
(Centro de Investigación y de Estudios Avanzados del IPN, México, DF, 1992, 1992-02-15)Esta monografía es un curso doctoral impartido en el CInvEstAv del Instituto Politécnico Nacional en México, DF, durante el año académico 1991-92 (con licencia sabática de la UCR) y luego redactado como publicación ... -
The asymptotic distribution of Andrews’ smallest parts function
(2015-12)In this paper, we use methods from the spectral theory of automorphic forms to give an asymptotic formula with a power saving error term for Andrews’ smallest parts function spt(n). We use this formula to deduce an asymptotic ... -
The Chowla-Selberg formula for abelian CM fields and Faltings heights
(2016-03)In this paper we establish a Chowla-Selberg formula for abelian CM fields. This is an identity which relates values of a Hilbert modular function at CM points to values of Euler’s gamma function Γ and an analogous function ... -
The Error in an Alternating Series
(2018-03)We present a new proof of Johnsonbaugh’s estimates for the error in an alternating series based on an idea of R. M. Young. We also use this same idea to prove the convergence of the Euler transform and a corresponding error ... -
The Gromov’s centralizer theorem for semisimple Lie group actions
(2017-10)We give a new version of the Gromov’s centralizer theorem in the case of semisimple Lie group actions and arbitrary rigid geometric structures of algebraic type. -
The role of short-term immigration on disease dynamics: An SIR model with age-structure
(2019-02-18)We formulate an age-structured nonlinear partial differential equation model that features short-term immigration effects in a population. Individuals can immigrate into the population as any of the three stages in the ... -
Tres caminos hacia la geometría elemental
(Congreso CANP 2012: "Construcción de Capacidades en Matemáticas y Educación Matemática", 2012-08)La enseñanza de la geometría a nivel preuniversitaria suscita debates sobre su fundamentación, su puesta en práctica y su engranaje con otros áreas de la matemática. Aquí se ofrecen algunas ideas para explorar de qué ... -
Uniform sparse bounds for discrete quadratic phase Hilbert transforms
(2017-09)Consider the discrete quadratic phase Hilbert Transform acting on $\ell^{2}(\mathbb{Z})$ finitely supported functions $$ H^{\alpha} f(n) : = \sum_{m \neq 0} \frac{e^{i\alpha m^2} f(n - m)}{m}. $$ We prove that, ... -
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 ... -
XIX Simposio Internacional de Métodos Matemáticos Aplicados a las Ciencias
(2014-05-02)El XIX° Simposio Internacional de Métodos Matemáticos Aplicados a las Ciencias (XIX SIMMAC) es el evento de matemática aplicada más importante de América Central. Es organizado por el Centro de Investigación en Matemática ...
