Homomorphic encoders of profinite abelian groups I
(Elsevier, 2023-05)
Let {Gi |i ∈ N} be a family of finite Abelian groups. We say that a subgroup
G ≤
i∈N
Gi is order controllable if for every i ∈ N there is ni ∈ N such that for
each c ∈ G, there exists a ∈ G satisfying that a|[1,i] = ...
Comprensión del conjunto solución de un sistema de ecuaciones lineales de dos incógnitas: un estudio de casos

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 ...
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 ...
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 ...
[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, ...
Hölder regularity for the Moore-Gibson-Thompson equation with infinite delay
(American Institute of Mathematical Sciences (AIMS), 2018-01)
We characterize the well-posedness of a third order in time equation with infinite delay in Holder spaces, solely in terms of spectral properties concerning the data of the problem. Our analysis includes the case of the ...
Complete invariant fuzzy metrics on groups
(Elsevier, 2018-01-01)
We
study some questions related to complete fuzzy metric topological groups (in the sense of Kramosil and Michael). Invariant
fuzzy metrics are characterized and we prove that if (G, M, ∗) is a fuzzy metric group such ...
Discrete maximal regularity for Volterra equations and nonlocal time-stepping schemes
(American Institute of Mathematical Sciences, 2020)
In this paper we investigate conditions for maximal regularity of Volterra equations defined on the Lebesgue space of sequences ‘p(Z) by using Bl¨unck’s theorem on the
equivalence between operator-valued ‘p-multipliers ...
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) ...
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 ...
