Continuity of multiplication of distributors

open access: yesInternational 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.

Dual Space Approach to Cyber harm and Religion: Attitudes and Experiences [PDF]

open access: yesReligion & Communication, 2013
What is the relationship between pathological study of experiences the Iranian cyberspace users, and their religious and ethical beliefs? Is it possible to locate a significant relationship between different levels of religiousness, and pathological ...

Dual spaces of local Morrey-type spaces [PDF]

open access: yesCzechoslovak Mathematical Journal, 2011
Let \(\omega \) be a weight function on \((0,\infty )\). The local Morrey-type spaces \(LM_{p,\theta ,\omega }\) with the norm \(\| \omega (r)\| f\| _{L_p(B(0,r))}\| _{L_{\theta }(0,\infty )}\) are considered.

Spaces of compact operators which are M-ideals in L(X,Y)

open access: yesInternational 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

open access: yesInternational 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 ...

Global monopole as dual-vacuum solution in Kaluza-Klein spacetime [PDF]

open access: yes, 1999
By application of the duality transformation, which implies interchange of active and passive electric parts of the Riemann curvature (equivalent to interchange of Ricci and Einstein tensors) it is shown that the global monopole solution in the Kaluza ...

The dual space of β(Γ)

open access: yesInternational 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 ...

Dual Transformations in Galilean Spaces

open access: yesInternational 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 $G^{3}_{1}$.

Vortex solutions in the noncommutative torus [PDF]

open access: yes, 2006
Vortex configurations in the two-dimensional torus are considered in noncommutative space. We analyze the BPS equations of the Abelian Higgs model. Numerical solutions are constructed for the self-dual and anti-self dual cases by extending an algorithm ...
