Differential inclusions of arbitrary fractional order with anti-periodic conditions in Banach spaces

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
In this paper, we establish various existence results of solutions for fractional differential equations and inclusions of arbitrary order $q\in (m-1,m)$, where $m$ is an arbitrary natural number greater than or equal to two, in infinite dimensional ...

Statistical Order Convergence and Statistically Relatively Uniform Convergence in Riesz Spaces

open access: yesJournal of Function Spaces, 2018
A new concept of statistically e-uniform Cauchy sequences is introduced to study statistical order convergence, statistically relatively uniform convergence, and norm statistical convergence in Riesz spaces.

(p,q)-Regular operators between Banach lattices [PDF]

open access: yes, 2019
[EN] We study the class of (p,q)-regular operators between quasi-Banach lattices. In particular, a representation of this class as the dual of a certain tensor norm for Banach lattices is given.

Some properties of b-weakly compact operators on Banach lattices

open access: yesپژوهش‌های ریاضی, 2021
In this paper we give some necessary and sufficient conditions for which each Banach lattice  is    space and we study some properties of b-weakly compact operators from a Banach lattice  into a Banach space .

Banach Lattices

open access: yes, 2023
The main goal of this thesis is to find conditions, under which, Banach Lattices are isomorphic either to C(K), where K is compact, or to L1(μ), with respect to the measure μ. In Chapter 1, we give some basic notations and definitions for vector lattices.

Lower 2-estimates for sequences in Banach lattices

open access: yes, 1991
We characterize Banach lattices in which every bounded sequence contains a subsequence which either converges in norm or satisfies a lower 2 2 -estimate. As a consequence we obtain, for the class of all Banach lattices, a positive answer

Proximity measures in symbolic data analysis

open access: yesStatistica, 2007
The Authors consider the general problem of similarity and dissimilarity measures in Symbolic Data Analysis. First of all they examine the classical definitions of elementary event, assertion object, hierarchical dependences and logical dependences. Then

Irreducible Operators and Semigroups on Banach Lattices

open access: yes, 2013
In this thesis, I study irreducibility on Banach lattices. First, I study irreducible positive operators on Banach lattices. I develop a uniform approach to several comparison theorems of positive operators.
