La geometría en su contexto histórico 

Várilly Boyle, Joseph C. (Las Matemáticas y su Enseñanza 6(17):21–34, 1995 octubre, 1995-10-15)
La geometría en los sistemas de enseñanza media ha sido retomado por diversas propuestas para remozar los programas de matemáticas; y en el caso de Costa Rica, con la puesta en práctica de un programa ambicioso que destaca ...

Comparative analysis of dengue versus chikungunya outbreaks in Costa Rica 

Sánchez Peña, Fabio Ariel; Barboza Chinchilla, Luis Alberto; Burton, David; Cintrón Arias, Ariel (2018-06)
For decades, dengue virus has been a cause of major public health concern in Costa Rica, due to its landscape and climatic conditions that favor the circumstances in which the vector, Aedes aegypti, thrives. The emergence ...

Nori fundamental gerbe of essentially finite covers and Galois closure of towers of torsors 

Antei, Marco; Biswas, Indranil; Emsalem, Michel; Tonini, Fabio; Zhang, Lei (2019)
We prove the existence of a Galois closure for towers of torsors under finite group schemes over a proper, geometrically connected and geometrically reduced algebraic stack X over a field k. This is done by describing the ...

Models of torsors over affine spaces 

Antei, Marco; Esquivel Araya, Jorge Arturo (2019)
Let X := A n R be the n-dimensional affine space over a discrete valuation ring R with fraction field K. We prove that any pointed torsor Y over A n K under the action of an affine finite-type group scheme can be extended ...

The pseudo-fundamental group scheme 

Antei, Marco; Dey, Arijit (2019)
Let X be any scheme defined over a Dedekind scheme S with a given section x ∈ X (S). We prove the existence of a pro-finite S-group scheme א (X,x) and a universal א (X,x)-torsor dominating all the pro-finite pointed torsors ...

Vertical Transmission in a Two-Strain Model of Dengue Fever 

Murillo, David; Holechek, Susan A.; Murillo, Anarina L.; Sánchez Peña, Fabio Ariel; Castillo Chávez, Carlos (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 ...

The asymptotic distribution of Andrews’ smallest parts function 

Banks, Josiah; Barquero Sánchez, Adrián Alberto; Masri, Riad; Sheng, Yan (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 ...

Uniform sparse bounds for discrete quadratic phase Hilbert transforms 

Kesler, Robert; Mena Arias, Darío Alberto (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, ...

On the Colmez conjecture for non-abelian CM fields 

Barquero Sánchez, Adrián Alberto; Masri, Riad (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 ...

The Chowla-Selberg formula for abelian CM fields and Faltings heights 

Barquero Sánchez, Adrián Alberto; Masri, Riad (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 ...
