Banach Lattice Structures and Concavifications in Banach Spaces

open access: yesMathematics, 2020
Let ( Ω , Σ , μ ) be a finite measure space and consider a Banach function space Y ( μ ) . We say that a Banach space E is representable by Y ( μ ) if there is a continuous bijection I : Y ( μ ...

A function space integral for a Banach space of functionals on Wiener space [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
In an earlier paper the authors established the existence of Cameron and Storvick's function space integral J,(F) for a class of finite-dimensional functionals F. Here we consider a space A of not necessarily finite-dimensional functionals generated by the earlier functionals.

A peculiar Banach function space [PDF]

open access: yesProceedings of the American Mathematical Society, 1965
Let (S, E, ,u) be a a-finite measure space. A length function on (S, E, ,u) is a non-negative, extended-real-valued function X on the set P=P(S, E, ,u) of non-negative, real-valued, 2-measurable functions on S such that (1) X(f) = Of = O a.e. (u); (2) X(f+g) ? (f) 1f (f); (5) E C Y, ,ut (E) 0DfEfdA -?< aX (f) for all f CP.

Banach spaces of GLT sequences and function spaces

open access: yesThe Electronic Journal of Linear Algebra, 2022
Generalized locally Toeplitz (GLT) sequences of matrices originated from the spectral study of certain partial differential equations. To be more precise, such matrix sequences arise when we numerically approximate either partial differential equations or fractional differential equations using any discretization by local methods (finite differences ...

Application of a New Class of Characteristic Function

open access: yesJournal of Harbin University of Science and Technology, 2021
In Banach space,considering introducing a new class of real characteristic functions fx + ty ( y) and fx + ty ( y) ,the independent variable is t,and the domain is [0,+ ∞ ) ,and the corresponding properties of those new characteristic functions are used ...

Weighted Vector-Valued Holomorphic Functions on Banach Spaces

open access: yesAbstract and Applied Analysis, 2013
We study the weighted Banach spaces of vector-valued holomorphic functions defined on an open and connected subset of a Banach space. We use linearization results on these spaces to get conditions which ensure that a function f defined in a subset A of ...

The Banach-Saks Properties in Orlicz-Lorentz Spaces

open access: yesAbstract and Applied Analysis, 2014
The Banach-Saks index of an Orlicz-Lorentz space Λφ,w(I) for both function and sequence case, is computed with respect to its Matuszewska-Orlicz indices of φ. It is also shown that an Orlicz-Lorentz function space has weak Banach-Saks (resp., Banach-Saks)

Multipliers of Banach valued weighted function spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We generalize Banach valued spaces to Banach valued weighted function spaces and study the multipliers space of these spaces. We also show the relationship between multipliers and tensor product of Banach valued weighted function spaces.

Shape Transformation Approaches for Fluid Dynamic Optimization

open access: yesAerospace, 2023
The contribution is devoted to combined shape- and mesh-update strategies for parameter-free (CAD-free) shape optimization methods. Three different strategies to translate the shape sensitivities computed by adjoint shape optimization procedures into ...
