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 ...

Modeling spatial dependencies of natural hazards in coastal regions: a nonstationary approach with barriers
Springer (2023)Natural hazards like floods, cyclones, earthquakes, or, tsunamis have deep impacts on the environment and society causing damage to both life and property. These events can cause widespread destruction and can lead to ...

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 and improved orbits of historical comets: Late 4th and 5th century
Elsevier (2022-05-22)Since as early as the 19th century, many scholars have devoted themselves to the calculation of sets of orbital elements for particular historical comets. In many cases, these studies have led to proposing orbits that have ...

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 ...

No-go theorems for photon state transformations in quantum linear optics
Elsevier (2023)We give a necessary condition for photon state transformations in linear optical setups preserving the total number of photons. From an analysis of the algebra describing the quantum evolution, we find a conserved quantity ...

Norm-Attaining Tensors and Nuclear Operators
Springer (2022-06)Given two Banach spaces X and Y, we introduce and study a concept of norm-attainment in the space of nuclear operators (𝑋�,𝑌�) and in the projective tensor product space 𝑋�⊗ˆ𝜋�𝑌�. We exhibit positive and negative ...

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 ...

Numerical integrators based on the Magnus expansion for nonlinear dynamical systems
Elsevier (2020-03-15)Explicit numerical integration algorithms up to order four based on the Magnus expansion for nonlinear non-autonomous ordinary differential equations are presented and tested on problems possessing qualitative (very often, ...

Occultation of Planets by the Moon in European Narrative Medieval Sources
Sage (2019-05)Existing research dealing with astronomical observations from medieval Europe have extensively covered topics such as solar and lunar eclipses and sightings of comets and meteors, but no compilation of occultations of ...

On interpolating sequences for Bloch type spaces
Elsevier (2022-02-14)When we deal with , it is known that interpolating sequences are interpolating and it is sufficient to interpolate idempotents of in order to interpolate the whole . We will extend these results to the frame of interpolating ...

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 ...

On norm-attainment in (symmetric) tensor products
Taylor & Francis (2022)In this paper, we introduce a concept of norm-attainment in the projective symmetric tensor product of a Banach space X, which turns out to be naturally related to the classical norm-attainment of N -homogeneous polynomials ...

On the Algebras VN(H) and VN(H)(*) of an Ultraspherical Hypergroup H
Cambridge University Press (2022-12-12)Let H be an ultraspherical hypergroup and let A(H) be the Fourier algebra associated with H. In this paper, we study the dual and the double dual of A(H). We prove among other things that the subspace of all ...
