Smoothness in Musielak-Orlicz Function Spaces Equipped with p-Amemiya Norm

open access: yesJournal of Harbin University of Science and Technology
The smoothness of Banach spaces is one of the important research content in the geometric theory of Banach spaces, which is closely related to the convexity of Banach spaces and the differentiability of norms.

A New Class of Banach Spaces and Its Relation with Some Geometric Properties of Banach Spaces

open access: yesAbstract and Applied Analysis, 2012
By introducing the concept of L-limited sets and then L-limited Banach spaces, we obtain some characterizations of it with respect to some well-known geometric properties of Banach spaces, such as Grothendieck property, Gelfand-Phillips property, and ...

Fragmentation–Coagulation Processes With Advection or Diffusion in Space

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a continuous fragmentation–coagulation model in which the reacting particles can be transported in physical space through either advection or diffusion. We prove new results on the generation of C0$$ {C}_0 $$‐semigroups with parameter and use them to show that the abstract Cauchy problem associated with a more ...

On Ideals in Banach Spaces

open access: yesRocky Mountain Journal of Mathematics, 2001
A subspace \(Y\) of a Banach space \(X\) is called to be an ideal in \(X\), if there is a norm one projection \(P :X^*\to X^*\) with \(Y^\perp=\text{ker }P\). By a result of \textit{Å. Lima} [Isr. Math. 84, No. 3, 451-475 (1993; Zbl 0814.46016)], this is equivalent of saying \(Y^{\perp\perp}\) is the range of a norm one projection in \(X^{**}\). In the

The dark side of categorical Banach space theory

open access: yesExtracta Mathematicae
This paper could be considered the third in the series The Hitchhiker Guide to Categorical Banach Space Theory [24, 25]. We explore (quasi) Banach space formulations and applications for advanced categorical topics, such as relative homology (with ...

Convolution Algebraic Structures Defined by Hardy-Type Operators

open access: yesJournal of Function Spaces and Applications, 2013
The main aim of this paper is to show that certain Banach spaces, defined via integral kernel operators, are Banach modules (with respect to some known Banach algebras and convolution products on ℝ+).

Non-solid cone b-metric spaces over Banach algebras and fixed point results of contractions with vector-valued coefficients

open access: yesOpen Mathematics, 2023
In this article, without requiring solidness of the underlying cone, a kind of new convergence for sequences in cone bb-metric spaces over Banach algebras and a new kind of completeness for such spaces, namely, wrtn-completeness, are introduced.
