Jugar, competir, entrenar: aprendiendo técnicas matemáticas
(Sociedad Canaria Isaac Newton de Profesores de Matemáticas, 2019)
Uno de los objetivos más importantes, tanto en los últimos cursos de educación
secundaria como en los primeros cursos de matemáticas en los grados de ingeniería o
los de ciencias experimentales y ciencias económicas, es ...
Some properties of local weighted second-order statistics for spatio-temporal point processes
(Springer, 2020)
Diagnostics of goodness-of-fit in the theory of point processes are often considered through the transformation of data into
residuals as a result of a thinning or a rescaling procedure. We alternatively consider here ...
Arithmetical Conditions on Invariant Sylow Numbers
(Springer Verlag, 2018)
Let A and G be finite groups and suppose that A acts coprimely on G via automorphisms. A natural number n is said to be an A-invariant Sylow number if n is the number of A-invariant Sylow p-subgroups of G for some prime ...
On convergent sequences in dual groups
(Real Academia de Ciencias Exactas, Físicas y Naturales, 2020-01-16)
We provide some characterizations of precompact abelian groups G
whose dual group G∧
p
endowed with the pointwise convergence topology on elements of G contains a nontrivial convergent sequence. In
the special case of ...
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 ...
Generalized Linear Models for Geometrical Current predictors. An application to predict garment fit
(SAGE Publications, 2019)
The aim of this paper is to model an ordinal response variable in terms
of vector-valued functional data included on a vector-valued RKHS. In particular,
we focus on the vector-valued RKHS obtained when a geometrical ...
Assessment of facial harmony among Caucasian Spaniards 18 to 60 years of age and its relationship with the golden ratio
(Springer, 2018-04)
Background
Throughout history, the perception and defini-
tion of beauty and attractiveness have changed and have been
influenced by cultural norms. This article analyzes the concept
of

Conjugacy classes and union of cosets of normal subgroups
(Springer Nature, 2023)
Let G be a finite group, N a normal subgroup of G and K a conjugacy class of G. We prove that if K∪K−1 is union of cosets of N, then N is soluble, K is a real-imaginary class, that is, every irreducible character of G takes ...
Order of products of elements in finite groups
(WileyLondon Mathematical Society, 2018-10)
If G is a finite group, p is a prime, and x∈G, it is an interesting problem to place x in a convenient small (normal) subgroup of G, assuming some knowledge of the order of the products xy, for certain p‐elements y of G.
A Survey of Meteoric Activity over Spain during the Eighth–Fifteenth Centuries
(SAGE Publications, 2016)
The lack of astronomical observations from Medieval and early Modern Spanish sourcesis a constant in the records of solar eclipses, meteors and other celestial phenomena. This may be partially explained by the absence of ...
