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 ...
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 ...
A Unifying Framework for Perturbative Exponential Factorizations
(MDPI, 2021-03-17)
We propose a framework where Fer and Wilcox expansions for the solution of differential
equations are derived from two particular choices for the initial transformation that seeds the product
expansion. In this scheme, ...
A Modified SIRD Model to Study the Evolution of the COVID-19 Pandemic in Spain
(Multidisciplinary Digital Publishing Institute, 2021-04-19)
In this paper, we use an SIRD model to analyze the evolution of the COVID-19 pandemic in
Spain, caused by a new virus called SARS-CoV-2 from the coronavirus family. This model is governed
by a nonlinear system of ...
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 ...
Asymmetric Entanglement-Assisted Quantum Error-Correcting Codes and BCH Codes
(IEEE, 2020-01-17)
The concept of asymmetric entanglement-assisted quantum error-correcting code (asymmetric EAQECC) is introduced in this article. Codes of this type take advantage of the asymmetry in quantum errors since phase-shift errors ...
Transitivity in Fuzzy Hyperspaces
(MDPI, 2020)
Given a metric space (X, d), we deal with a classical problem in the theory of hyperspaces:
how some important dynamical properties (namely, weakly mixing, transitivity and point-transitivity)
between a discrete dynamical ...
Challenges Regarding Scientific Transcription in Virtual Office Hours
(MDPI, 2021-03-24)
Mathematics teachers face great difficulties during virtual communication with their
students, mainly because scientific and technical subjects use a great many mathematical symbols,
abstract objects and a wide variety ...
Dynamical mechanism behind ghosts unveiled in a map complexification
(Elsevier, 2022-01-14)
Complex systems such as ecosystems, electronic circuits, lasers, or chemical reactions can be modelled by dynamical systems which typically experience bifurcations. It is known that transients become extremely long close ...
Locally recoverable J-affine variety codes
(2020-06)
A locally recoverable (LRC) code is a code over a finite eld Fq such that
any erased coordinate of a codeword can be recovered from a small number of other
coordinates in that codeword. We construct LRC codes correcting ...
