Observations on the Separable Quotient Problem for Banach Spaces
Axioms, 2020 The longstanding Banach−Mazur separable quotient problem asks whether every infinite-dimensional Banach space has a quotient (Banach) space that is both infinite-dimensional and separable.

LW∗W-property and topological centers of banach algebras [PDF]
Journal of Hyperstructures, 2012 In this paper we introduce the new concepts LW∗Wproperty and RW∗W-property for a Banach algebra A. Under certain conditions, we show that if A has LW∗W-property and RW∗W- property, then A is Arens regular.

Dual spaces of weighted spaces [PDF]
Transactions 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 ...

Dual Transformations in Galilean Spaces
International Electronic Journal of Geometry, 2020 In this study, we define a dual transformation between $G^{n}$ and $G^{n}_{1}$. We examine the invariance of the plane where the shear motion is acting in Galilean and pseudo-Galilean spaces. We define a dual transformation between $\widehat{G^{n}}$ and $\widehat{G^{n}_{1}}$ as well. We provide applications in $G^{3}$ and $G^{3}_{1}$.

Singularities of the Ruled Surfaces According to RM Frame and Natural Lift Curves
Cumhuriyet Science Journal, 2022 In this study, the ruled surface generated by the natural lift curve in IR^3 is obtained by using the isomorphism between unit dual sphere, DS^2 and the subset of the tangent bundle of unit 2-sphere, T\bar{M}. Then, exploitting E.

Continuity of multiplication of distributors
International Journal of Mathematics and Mathematical Sciences, 1981 In a reference book for distributions [1], it is shown that the multiplication (u,f)↦uf on C∞×𝒟′, as well as on 𝒪M×𝒮′, is hypocontinuous. We show here that in both cases it is discontinuous.

Spaces of compact operators which are M-ideals in L(X,Y)
International Journal of Mathematics and Mathematical Sciences, 1992 Suppose X and Y are reflexive Banach spaces. If K(X,Y), the space of all compact linear operaters from X to Y is an M-ideal in L(X,Y), the space of all bounded linear operators from X to Y, then the second dual space K(X,Y)** of K(X,Y) is isometrically ...

Iterated Stieltjes transform of generalized functions
International Journal of Mathematics and Mathematical Sciences, 1985 The generalized S2-transform of a member of f of a certain space of generalized functions is defined as F(x)=〈f(t),k(x,t;ρ)〉, wherek(x,t;ρ)=∫0∞1(x+y)ρ(y+t)ρ dy, ρ>12 ...

International Journal of Mathematics and Mathematical Sciences, 1997 The space of Boehmians with Δ-convergence is a complete topological vector space in which the topology is induced by an invariant metric. We show that the dual space of the space of periodic Boehmians can be identified with the class of trigonometric ...
