Statistical convergence in vector lattices [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2023
The statistical convergence is defined for sequences with the asymptotic density on the natural numbers, in general. In this paper, we introduce the statistical convergence in vector lattices by using the finite additive measures on directed sets ...

Application of ${\rm (L)$ sets to some classes of operators} [PDF]

open access: yesMathematica Bohemica, 2016
The paper contains some applications of the notion of $L$ sets to several classes of operators on Banach lattices. In particular, we introduce and study the class of order ${\rm (L)$-Dunford-Pettis operators, that is, operators from a Banach space into a

Perturbative matching of continuum and lattice quasi-distributions

open access: yesEPJ Web of Conferences, 2018
Matching of the quasi parton distribution functions between continuum and lattice is addressed using lattice perturbation theory specifically withWilson-type fermions.

The ALF (Algorithms for Lattice Fermions) project release 1.0. Documentation for the auxiliary field quantum Monte Carlo code

open access: yesSciPost Physics, 2017
The Algorithms for Lattice Fermions package provides a general code for the finite temperature auxiliary field quantum Monte Carlo algorithm. The code is engineered to be able to simulate any model that can be written in terms of sums of single-body ...

Orthogonally Biadditive Operators

open access: yesJournal of Function Spaces, 2021
In this article, we introduce and study a new class of operators defined on a Cartesian product of ideal spaces of measurable functions. We use the general approach of the theory of vector lattices.

Between quantum logic and concurrency [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
We start from two closure operators defined on the elements of a special kind of partially ordered sets, called causal nets. Causal nets are used to model histories of concurrent processes, recording occurrences of local states and of events. If every

Pawlak Algebra and Approximate Structure on Fuzzy Lattice

open access: yesThe Scientific World Journal, 2014
The aim of this paper is to investigate the general approximation structure, weak approximation operators, and Pawlak algebra in the framework of fuzzy lattice, lattice topology, and auxiliary ordering.

Faddeev equation and its symmetric version for a three-particle lattice hamiltonian [PDF]

open access: yesE3S Web of Conferences
In the present paper we consider the three-particle lattice Hamiltonian associated to a system of three particles on the d-dimensional lattice, where the role of two-particle discrete Schroedinger operators is played by a family of Friedrichs models.

Polymatroids, Closure Operators and Lattices

open access: yesOrder, 2022
We study the closure operators of polymatroids from a lattice theoretic point of view. We show that polymatroid closure operators relate to lattices enriched with a generating set in the same way that matroids relate to geometric lattices. Through this relation we define a notion of minors for lattices enriched with a generating set. For the lattice of

Matrices related to some Fock space operators [PDF]

open access: yesOpuscula Mathematica, 2011
Matrices of operators with respect to frames are sometimes more natural and easier to compute than the ones related to bases. The present work investigates such operators on the Segal-Bargmann space, known also as the Fock space.
