Completeness, metrizability and compactness in spaces of fuzzy-number-valued functions
(Elsevier, 2018-05-15)
Fuzzy-number-valued functions, that is, functions defined on a topological space taking values in the space of fuzzy numbers, play a central role in the development of Fuzzy Analysis. In this paper we study completeness, ...
Quasi-cyclic constructions of quantum codes
(Elsevier, 2018-07)
We give sufficient conditions for self-orthogonality with respect to symplec-
tic, Euclidean and Hermitian inner products of a wide family of quasi-cyclic codes of index
two. We provide lower bounds for the symplectic ...
Multiple photon effective Hamiltonians in linear quantum optical networks
(Elsevier, 2019)
We give an alternative derivation for the explicit formula of the effective Hamiltonian describing the evolution
of the quantum state of any number of photons entering a linear optics multiport. The description is based ...
New binary and ternary LCD codes
(IEEE, 2018-05-09)
LCD codes are linear codes with important cryptographic applications. Recently, a method has been presented
to transform any linear code into an LCD code with the same parameters when it is supported on a finite field ...
Computing the Matrix Exponential with an Optimized Taylor Polynomial Approximation
(MDPI, 2019)
A new way to compute the Taylor polynomial of a matrix exponential is presented
which reduces the number of matrix multiplications in comparison with the de-facto standard
Paterson-Stockmeyer method for polynomial ...
Singular perturbations of Blaschke products and connectivity of Fatou components
(American Institute of Mathematical Sciences (AIMS), 2017)
The goal of this paper is to study the family of singular perturbations of Blaschke products given by Ba,λ(z)=z3z−a1−a¯z+λz2. We focus on the study of these rational maps for parameters a in the punctured disk D∗ and |λ| ...
Novel symplectic integrators for the Klein-Gordon equation with space- and time-dependent mass
(Elsevier, 2019-04)
We consider the numerical time-integration of the non-stationary Klein–Gordon equation with position- and time-dependent mass. A novel class of time-averaged symplectic splitting methods involving double commutators is ...
The Lie-group method based on radial basis functions for solving nonlinear high dimensional generalized Benjamin–Bona–Mahony–Burgers equation in arbitrary domains
(Elsevier, 2018-03-15)
The aim of this paper is to introduce a new numerical method for solving the nonlinear generalized Benjamin–Bona–Mahony–Burgers (GBBMB) equation. This method is combination of group preserving scheme (GPS) with radial basis ...
Could Plant Hormones Provide a Reliable Tool for Early Detection of Rhynchophorus ferrugineus (Coleóptera: Curculionidae) Infested Palms?
(Entomological Research Society, 2019-03)
Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae) is one of the most important pest of palms worldwide. A serious management problem is the difficulty of detecting early infestation stages, which is critical ...
Global and Local Three-dimensional Studies of The Residual Vector Field from 2MASS and Hipparcos-2 Catalog
(Astronomical Society of the PacificIOP, 2019-04)
The Gaia mission will provide a six-parameter solution for millions of stars, including a tridimensional map of our Galaxy. The estimation of distances has been made for the Tycho-Gaia Astrometric Solution (TGAS), while ...
