Property (h) of Banach Lattice and Order-to-Norm Continuous Operators

open access: yesMathematics, 2023
In this paper, we introduce the property (h) on Banach lattices and present its characterization in terms of disjoint sequences. Then, an example is given to show that an order-to-norm continuous operator may not be σ-order continuous.

The Order Continuity of the Regular Norm on Regular Operator Spaces [PDF]

open access: yesAbstract and Applied Analysis, 2013
We present here some sufficient conditions for the regular norm on to be order continuous, and for () to be a KB-space. In particular we deduce a characterization of the order continuity of the regular norm using L- and M-weak compactness of regular ...

Unbounded order-norm continuous and unbounded norm continuous operator

open access: yesFilomat, 2021
A continuous operator T between two normed vector lattices E and F is called unbounded order-norm continuous whenever x? uo? 0 implies ||Tx?|| ? 0, for each norm bounded net (x?)? ? E. Let E and F be two Banach lattices. A continuous operator T : E ? F is called unbounded norm continuous, if for each norm bounded net (x?)? ? E, x? un?

On order isomorphisms of norm attainment sets of continuous functions

open access: yesActa Mathematica Hungarica
Abstract We provide a method for reconstructing the underlying locally compact Hausdorff space of an algebra of continuous functions vanishing at infinity, using the norm attainment sets of continuous functions. As an application, it is demonstrated that an order isomorphism of norm attainment sets between spaces of continuous functions ...

Some properties of weak Banach-Saks operators [PDF]

open access: yesMathematica Bohemica, 2021
We establish necessary and sufficient conditions under which weak Banach-Saks operators are weakly compact (respectively, {\rm L}-weakly compact; respectively, {\rm M}-weakly compact).

On regular operators on Banach Lattices

open access: yesActa et Commentationes: Ştiinţe Exacte şi ale Naturii, 2023
Let E and F be Banach lattices and X and Y be Banach spaces. A linear operator T:E->F is called regular if it is the difference of two positive operators. We show that F has a b-property if and only if Lr(E,F) has b-property.

Formal balls of Q-categories [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2023
The construction of the formal ball model for metric spaces due to Edalat and Heckmann was generalized to Q-categories by Kostanek and Waszkiewicz, where Q is a commutative and unital quantale.

The Class of Demi-Order Norm Continuous Operators

open access: yesGazi University Journal of Science, 2023
In this paper, we introduce the class of demi-order norm continuous operator on a normed Riesz space. We study the relationship between order-to-norm continuous operator and demi-order norm continuous operator. We also investigate some properties of the class of demi-order norm continuous operator, and it is given a characterization of a normed Riesz ...
