Foliations with isolated singularities on Hirzebruch surfaces
(De Gruyter, 2021)
We study foliations ℱ on Hirzebruch surfaces Sδ and prove that, similarly to those on the projective plane, any ℱ can be represented by a bi-homogeneous polynomial affine 1-form. In case ℱ has isolated singularities, we ...
Interpolation sets in spaces of continuous metric-valued functions
(Elsevier, 2018-10)
Let X and K be a Cech-complete topological group and a compact group, ˇ
respectively. We prove that if G is a non-equicontinuous subset of CHom(X; K), the set
of all continuous homomorphisms of X into K, then there is a ...
On Multi-Index Filtrations Associated to Weierstraß Semigroups
(Springer, Cham, 2020-05-14)
This paper is a survey on the main techniques involved in the computation of the Weierstraß semigroup at several points of curves defined over perfect fields, with special emphasis on the case of two points. Some hints ...
Clustering constrained on linear networks
(Springer, 2023)
An unsupervised classification method for point events occurring on a geometric network is proposed. The idea relies on
the distributional flexibility and practicality of random partition models to discover the clustering ...
Applying splitting methods with complex coefficients to the numerical integration of unitary problems
(American Institute of Mathematical Sciences (AIMS), 2022)
We explore the applicability of splitting methods involving complex coefficients to solve numerically the time-dependent Schr¨odinger equation.
We prove that a particular class of integrators are conjugate to unitary ...

En este artículo se reporta cómo estudiantes chilenos, de secundaria y
universitarios, comprenden el Conjunto Solución de un Sistema de Ecuaciones
Lineales de tres ecuaciones y dos incógnitas (CSSEL3x2). El estudio se ...
The weak compactification of locally compact groups
(Elsevier, 2021)
We further investigate the weak topology generated by the irreducible unitary representations of a group G. A deep result due to Ernest [13] and Hughes [22] asserts that every weakly compact subset of a locally compact ...
Composition Methods for Dynamical Systems Separable into Three Parts
(MDPI, 2020)
New families of fourth-order composition methods for the numerical integration of initial
value problems defined by ordinary differential equations are proposed. They are designed when
the problem can be separated into ...
A dichotomy property for locally compact groups
(Elsevier, 2018-08)
We extend to metrizable locally compact groups Rosenthal's theorem describing those Banach spaces containing no copy of l1. For that purpose, we transfer to general locally compact groups the notion of interpolation (Io) ...
[S]-linear and convex structures in function families
(Elsevier, 2019)
In this paper, the notion of [S]-lineability (originally coined
by Vladimir I. Gurariy) is introduced and developed in a general abstract
setting. This new notion is, then, applied to specific situations, as for
instance, ...
