Some results on asymptotically normable Frechet spaces [PDF]

Bibechana, 2010
In this paper, it is shown that the asymptotically normable spaces are the smallest class of Frechet spaces which contains the nuclear Kothe spaces with continuous norm, the Banach spaces and is closed under e-tensor products and sub-spaces.

Weakly compactly generated Frechet spaces [PDF]

International Journal of Mathematics and Mathematical Sciences, 1979
It is proved that a weakly compact generated Frechet space is Lindelöf in the weak topology. As a corollary it is proved that for a finite measure space every weakly measurable function into a weakly compactly generated Frechet space is weakly equivalent

Admissibility of Frechét spaces

Journal of Applied Mathematics and Computational Mechanics
The aim of this paper is to to show the admissibility of some class of Frechet spaces (see Definition 2.3). In particular, this generalizes the main results of [3]. As an application, we show the admissibility of a large class modular spaces equipped with F-norms determined in Theorem 4.1.

Gateaux and Frechet Derivative In Neutrosophic Normed Linear Spaces [PDF]

Neutrosophic Sets and Systems, 2023
In this study, we present the neutrosophic derivatives, the neutrosophic Gateaux derivative, and the neutrosophic Frechet derivative, and we examine some of their features. The relationship between the neutrophilic Frechet derivative and the neutrophilic

Approximation of analytic functions of exponential derived and integral bases in Fréchet spaces [PDF]

Assiut University Journal of Multidisciplinary Scientific Research, 2022
The purpose of this paper is to establish some theorems on the representation of analytic functions by exponential derived bases (EDBs) and exponential integral bases (EIBs) in Fréchet spaces.

On Twisted Frechet and (LB)-Spaces [PDF]

Proceedings of the American Mathematical Society, 1990
We study twisted Frechet spaces as well as twisted (LB)-spaces. We prove that a twisted space can have a nontwisted dual and that twisted spaces of a special class cannot be complemented in nontwisted spaces. We also give new examples of twisted spaces.

Stability of Set Differential Equations in Fréchet Spaces

Advances in Mathematical Physics, 2023
In this paper, we investigate the stability of set differential equations in Fréchet space F. Some comparison principles and stability criteria are established for set differential equations with the fact that every Fréchet space F is a projective limit ...

Entire Symmetric Functions on the Space of Essentially Bounded Integrable Functions on the Union of Lebesgue-Rohlin Spaces

Axioms, 2022
The class of measure spaces which can be represented as unions of Lebesgue-Rohlin spaces with continuous measures contains a lot of important examples, such as Rn for any n∈N with the Lebesgue measure.
