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 ...
Dynamics of subfamilies of Ostrowski–Chun methods
(Elsevier, 2020-09-25)
In this paper, we classify the fixed and critical points of the bi-parametric family of Ostrowski–Chun methods applied onquadratic polynomials. We obtain the values of the parameters that reduce the number ...
Eliahou number, Wilf function and concentration of a numerical semigroup
(Taylor & Francis, 2022-03-30)
We give an estimate of the minimal positive value of the Wilf function of a numerical semigroup in terms of its concentration. We describe necessary conditions for a numerical semigroup to have a negative Eliahou number ...
Exponential Perturbative Expansions and Coordinate Transformations
(MDPI, 2020)
We propose a unified approach for different exponential perturbation techniques used in
the treatment of time-dependent quantum mechanical problems, namely the Magnus expansion,
the Floquet–Magnus expansion for periodic ...
On using Reproducing Kernel Hilbert Spaces for the analysis of Replicated Spatial Point Processes
(Elsevier, 2023)
This paper focuses on the use of the theory of Reproducing
Kernel Hilbert Spaces in the statistical analysis of replicated point
processes. We show that spatial point processes can be observed
as random variables in a ...
A note on the Baker–Campbell–Hausdorff series in terms of right-nested commutators
(Springer, 2021-01-27)
We get compact expressions for the Baker–Campbell–Hausdorff
series Z = log(eX eY ) in terms of right-nested commutators. The reduction in the number of terms originates from two facts: (i) we use as a
starting point an ...
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 ...
Modeling Influence of Soil Properties in Different Gradients of Soil Moisture: The Case of the Valencia Anchor Station Validation Site, Spain
(Taylor and Francis, 2021-12-19)
The prediction of spatial and temporal variation of soil water content brings numerous
benefits in the studies of soil. However, it requires a considerable number of covariates to be included
in the study, complicating ...
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 ...
A review of spatiotemporal models for count data in R packages. A case study of COVID-19 data
(MDPI, 2021-07-01)
Spatiotemporal models for count data are required in a wide range of scientific fields, and they have become particularly crucial today because of their ability to analyze COVID-19- related data. The main objective of this ...
