Archetypal Curves in the Shape and Size Space: Discovering the Salient Features of Curved Big Data by Representative Extremes
(Springer, 2023)
Curves are complex data. Tools for visualizing, exploring, and discovering the structure
of a data set of curves are valuable. In this paper, we propose a scalable methodology to
solve this challenge. On the one hand, ...
The Constant of Interpolation in Bloch Type Spaces
(Springer, 2023-09)
It is known that there exists a constant 0 < Δ1 < 1 such
that any Δ1-separated sequence for the pseudohyperbolic distance in
the open unit disk D of C is interpolating for the classical Bloch space
B. We will prove that ...
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 ...
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 ...
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, ...
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 ...
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 ...
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 ...
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 ...
