Duality in Vector Lattices [PDF]

open access: yesProceedings of the American Mathematical Society, 1957
Introduction. We shall prove an abstract theorem on the duality of vector lattices. It is powerful and general enough to yield quickly the duality of both the classical examples of concrete vector lattices as well as various abstract analogs of these lattices.

Martingale-like sequences in Banach lattices

open access: yesModern Stochastics: Theory and Applications, 2018
Martingale-like sequences in vector lattice and Banach lattice frameworks are defined in the same way as martingales are defined in [Positivity 9 (2005), 437–456].

Multivariate Data Retrieval Modified by Random Noise using Lattice Autoassociative Memories with Eroded or Dilated Input Residuals [PDF]

open access: yesMATEC Web of Conferences, 2019
Lattice associative memories were proposed as an alternative approach to work with a set of associated vector pairs for which the storage and retrieval stages are based in the theory of algebraic lattices. Several techniques have been established to deal

Application of hourglass matrix in Goldreich-Goldwasser-Halevi encryption scheme

open access: yesJournal of Nigerian Society of Physical Sciences, 2022
Goldreich-Goldwasser-Halevi (GGH) encryption scheme is lattice-based cryptography with its security based on the shortest vector problem (SVP) and closest vector problem (CVP) with immunity to almost all attacks, including Shor's quantum algorithm and ...

Tensor-based trapdoors for CVP and their application to public key cryptography [PDF]

open access: yes, 1999
We propose two trapdoors for the Closest-Vector-Problem in lattices (CVP) related to the lattice tensor product.

Spin-helix-driven insulating phase in two-dimensional lattice

open access: yesPhysical Review Research, 2020
Motivated by emergent SU(2) symmetry in the spin-orbit-coupled system, we study the spin-helix-driven insulating phase in a two-dimensional lattice. When both Rashba and Dresselhaus spin-orbit couplings are present, the perfect Fermi-surface nesting ...

Vector - axial vector lattice cross section and valence parton distribution in the pion from a chiral quark model

open access: yesPhysics Letters B, 2020
Within a chiral quark model, we evaluate the good cross section in the Euclidean space in the vector - axial vector channel, proposed recently by Ma and Qiu as means to extract the so far elusive parton distribution functions of the pion from lattice QCD.

Orthogonality and complementation in the lattice of subspaces of a finite vector space [PDF]

open access: yesMathematica Bohemica, 2022
We investigate the lattice $ L( V)$ of subspaces of an $m$-dimensional vector space $ V$ over a finite field ${\rm GF}(q)$ with a prime power $q=p^n$ together with the unary operation of orthogonality.

Vector mixed-gap surface solitons [PDF]

open access: yes, 2006
We elucidate the properties of mixed-gap vector surface solitons supported by the interface between a uniform medium and an optical lattice imprinted in a Kerr-type nonlinear media.

Shear displacement gradient in X-ray Bragg coherent diffractive imaging

open access: yesJournal of Synchrotron Radiation, 2022
Bragg coherent X-ray diffractive imaging is a cutting-edge method for recovering three-dimensional crystal structure with nanoscale resolution. Phase retrieval provides an atomic displacement parallel to the Bragg peak reciprocal lattice vector.
