Fast Algorithms for the Computation of the Minimum Distance of a Random Linear Code
Association for Computing Machinery (ACM) (2019-06)The minimum distance of an error-correcting code is an important concept in information theory. Hence, computing the minimum distance of a code with a minimum computational cost is crucial to many problems in this area. ... -
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 ... -
Fuzzy quasi-pseudometrics on algebraic structures
Elsevier (2018-01)In this work we state a number of theorems about fuzzy (quasi-)pseudometrizable algebraic structures. Our most useful results are: (1) a fuzzy semitopological group whose topology is induced by a left-invariant fuzzy ... -
Generalisation of splitting methods based on modified potentials to nonlinear evolution equations of parabolic and Schrödinger type
Elsevier (2023-11-10)The present work is concerned with the extension of modified potential operator splitting methods to specific classes of nonlinear evolution equations. The considered partial differential equations of Schrödinger and ... -
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 ... -
Generalized Weierstrass semigroups and their Poincaré series.
Elsevier (2019-07)We investigate the structure of the generalized Weierstrass semigroups at several points on a curve defined over a finite field. We present a description of these semigroups that enables us to associate them with combinatorial ... -
Global and Local Three-dimensional Studies of The Residual Vector Field from 2MASS and Hipparcos-2 Catalog
Astronomical Society of the Pacific (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 ... -
High order integrators obtained by linear combinations of symmetric-conjugate compositions
Elsevier (2022-02-01)A new family of methods involving complex coefficients for the numerical integration of differential equations is presented and analyzed. They are constructed as linear combinations of symmetric-conjugate compositions ... -
Highly tempering infinite matrices
Springer Milan (2017-02)In this short note, it is proved the existence of in nite matrices that not only preserve convergence and limits of sequences but also convert every mem- ber of some dense vector space consisting, except for zero, of ... -
Homomorphic encoders of profinite abelian groups I
Elsevier (2023-05)Let {Gi |i ∈ N} be a family of finite Abelian groups. We say that a subgroup G ≤ i∈N Gi is order controllable if for every i ∈ N there is ni ∈ N such that for each c ∈ G, there exists a ∈ G satisfying that a|[1,i] = ... -
Hölder regularity for the Moore-Gibson-Thompson equation with infinite delay
American Institute of Mathematical Sciences (AIMS) (2018-01)We characterize the well-posedness of a third order in time equation with infinite delay in Holder spaces, solely in terms of spectral properties concerning the data of the problem. Our analysis includes the case of the ... -
Interpolation sets in spaces of continuous metric-valued functions
Elsevier (2018-10)Let X and K be a Cech-complete topological group and a compact group, ˇ respectively. We prove that if G is a non-equicontinuous subset of CHom(X; K), the set of all continuous homomorphisms of X into K, then there is a ... -
Invertibles in topological rings: a new approach
Springer (2021-11-15)Every element in the boundary of the group of invertibles of a Banach algebra is a topological zero divisor. We extend this result to the scope of topological rings. In particular, we define a new class of semi-normed ... -
Lipschitz continuity of the dilation of Bloch functions on the unit ball of a Hilbert space and applications
Springer (2024-02-13)Let BE be the open unit ball of a complex finite- or infinite-dimensional Hilbert space. If f belongs to the space B(BE ) of Bloch functions on BE , we prove that the dilation map given by x → (1 − x 2)R f (x) for x ∈ ... -
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 ... -
Lower bounds for the volume with upper bounds for the Ricci Curvature in dimension three
Wiley (2020)In this note, we provide several lower bounds for the volume of a geodesic ball within the injectivity radius in a 3‐dimensional Riemannian manifold assuming only upper bounds for the Ricci curvature. -
Maximal lp-regularity for discrete time Volterra equations with delay
Taylor & Francis (2019-07-08)In this paper, we investigate the existence and uniqueness of solutions belonging to the vector-valued space ℓp(Z,X) by using Blunck's theorem on the equivalence between operator-valued ℓp-multipliers and the notion of ... -
MDS, Hermitian almost MDS, and Gilbert–Varshamov quantum codes from generalized monomial-Cartesian codes
Springer Nature (2024-03-01)We construct new stabilizer quantum error-correcting codes from generalized monomial-Cartesian codes. Our construction uses an explicitly defined twist vector, and we present formulas for the minimum distance and dimension. ... -
Method to determine which quantum operations can be realized with linear optics with a constructive implementation recipe
American Physical Society (2019-08-02)The evolution of quantum light through linear optical devices can be described by the scattering matrix S of the system. For linear optical systems with m possible modes, the evolution of n input photons is given by a ... -
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 ...
