Geometry of Lebesgue-Bochner Function Spaces-Smoothness [PDF]

open access: yesTransactions of the American Mathematical Society, 1973
There exist real Banach spaces E such that the norm in E is of class C' away from zero; however, for any p, I < p < oo, the norm in the Lebesgue-Bochner function space LP(E, ,u) is not even twice differentiable away from zero. The main objective of this paper is to give a complete determination of the order of differentiability of the norm function in ...

Rotundity in Lebesgue-Bochner function spaces [PDF]

open access: yesTransactions of the American Mathematical Society, 1980
This paper concerns the isometric theory of the Lebesgue-Bochner function space L p ( μ , X ) {L^p}(\mu ,\,X) where 1 > p > ∞ 1 > p > \infty .

Property (H) in Lebesgue-Bochner Function Spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1985
We prove that if a Banach space X X has the property (HR) and if l 1 {l_1} is not isomorphic to a subspace of X X , then every point on the unit sphere of X X is a denting point of the closed unit ball.

Atomic Decompositions and John-Nirenberg Theorem of Grand Martingale Hardy Spaces with Variable Exponents

open access: yesJournal of Function Spaces, 2022
Let θ≥0 and p· be a variable exponent, and we introduce a new class of function spaces Lp·,θ in a probabilistic setting which unifies and generalizes the variable Lebesgue spaces with θ=0 and grand Lebesgue spaces with p·≡p and θ=1.

Multilinear Fourier multipliers on variable Lebesgue spaces [PDF]

open access: yes, 2014
In this paper, we study properties of the bilinear multiplier space. We give a necessary condition for a continuous integrable function to be a bilinear multiplier on variable exponent Lebesgue spaces. And we prove the localization theorem of multipliers

On the order of magnitude of Walsh-Fourier transform [PDF]

open access: yesMathematica Bohemica, 2020
For a Lebesgue integrable complex-valued function $f$ defined on $\mathbb R^+:=[0,\infty)$ let $\hat f$ be its Walsh-Fourier transform. The Riemann-Lebesgue lemma says that $\hat f(y)\to0$ as $y\to\infty$.

On the General and Measurable Solutions of some Functional Equations

open access: yesAnnales Mathematicae Silesianae, 2018
The general solutions of two functional equations, without imposing any regularity condition on any of the functions appearing, have been obtained. From these general solutions, the Lebesgue measurable solutions have been deduced by assuming the function(

Inclusion Properties of Henstock-Orlicz Spaces

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika), 2022
Henstock-Orlicz spaces were generally introduced by Hazarika and Kalita in 2021. In general, a function is Lebesgue integral if only if that function and its modulus are Henstock-Kurzweil integrable functions.

Resolvent estimates of elliptic differential and finite-element operators in pairs of function spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We present some resolvent estimates of elliptic differential and finite-element operators in pairs of function spaces, for which the first space in a pair is endowed with stronger norm. In this work we deal with estimates in (Lebesgue, Lebesgue), (Hölder,

Neutrosophic Non-Newtonian and Geometric Measures: A Consistent Analytical Framework [PDF]

open access: yesNeutrosophic Sets and Systems
The neutrosophic measure is a generalization of the classical measure in situations when the space contains some indeterminacy. In this paper, we introduce the concept of the Neutrosophic Geometric Measure, we also provide some results, and examples ...
