Dual Spaces of Multiparameter Local Hardy Spaces [PDF]

open access: yesJournal of Function Spaces, 2021
In this paper, we study the duality theory of the multiparameter local Hardy spaces hpℝn1×ℝn2, and we prove that hpℝn1×ℝn2∗=cmopℝn1×ℝn2, where cmopℝn1×ℝn2 are defined by discrete Carleson measure.

Noncommutative Phase Spaces by Coadjoint Orbits Method [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
We introduce noncommutative phase spaces by minimal couplings (usual one, dual one and their mixing). We then realize some of them as coadjoint orbits of the anisotropic Newton-Hooke groups in two- and three-dimensional spaces.

Almost and Strongly Almost B(r ̃,s ̃,t ̃,u ̃)- Summable Double Sequences

open access: yesEurasian Journal of Science and Engineering, 2021
In this paper, we define some new almost and strongly almost convergent double sequence spaces B ̃(C_f), B ̃(C_f0), B ̃[C_f] and B ̃[C_f0] derived by the domain of four-dimensional sequential band matrix B(r ̃,s ̃,t ̃,u ̃) in the spaces C_f, C_f0 , [C_f]

On locally Hilbert spaces [PDF]

open access: yesOpuscula Mathematica, 2016
This is an investigation of some basic properties of strictly inductive limits of Hilbert spaces, called locally Hilbert spaces, with respect to their topological properties, the geometry of their subspaces, linear functionals and dual spaces.

The dual of the space of bounded operators on a Banach space

open access: yesConcrete Operators, 2021
Given Banach spaces X and Y, we ask about the dual space of the 𝒧(X, Y). This paper surveys results on tensor products of Banach spaces with the main objective of describing the dual of spaces of bounded operators. In several cases and under a variety of

NEW APPROACHES ON DUAL SPACE [PDF]

open access: yesFacta Universitatis, Series: Mathematics and Informatics, 2020
In this paper, we give how to define the basic concepts of differential geometry on Dual space. For this, dual tangent vectors that have p as dual point of application are defined. Then, the dual analytic functions defined by Dimentberg are examined in detail, and by using the derivative of the these functions, dual directional derivatives and dual ...

Web spaces and worldwide web spaces: topological aspects of domain theory [PDF]

open access: yesLogical Methods in Computer Science, 2019
Web spaces, wide web spaces and worldwide web spaces (alias C-spaces) provide useful generalizations of continuous domains. We present new characterizations of such spaces and their patch spaces, obtained by joining the original topology with a second ...

Dual polar spaces of arbitrary rank [PDF]

open access: yes, 2011
In 1982 P. Cameron gave a characterisation of dual polar spaces of finite rank viewed as point-line spaces. This characterisation makes essential use of the fact that dual polar spaces of finite rank have finite diameter.

Dual spaces of weighted spaces [PDF]

open access: yesTransactions of the American Mathematical Society, 1970
The topological duals of a large class of weighted spaces of continuous functions are characterized as spaces of Radon measures which can be factored into a product of a weight function and a bounded Radon measure. We next obtain a representation for a base for the equicontinuous subsets of these dual spaces and for the extremal points of the members ...
