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 ...

Direct torque control for dual three-phase induction motor drives [PDF]

open access: yes, 2004
A direct torque control (DTC) strategy for dual three-phase induction motor drives is discussed in this paper. The induction machine has two sets of stator three-phase windings spatially shifted by 30 electrical degrees.

Dual-space Compressed Sensing

open access: yes, 2022
Compressed sensing (CS) is a powerful method routinely employed to accelerate image acquisition. It is particularly suited to situations when the image under consideration is sparse but can be sampled in a basis where it is non-sparse. Here we propose an

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 ...

Bäcklund transformations for noncommutative anti-self-dual Yang-Mills equations [PDF]

open access: yes, 2009
We present Bäcklund transformations for the non-commutative anti-self-dual Yang–Mills equations where the gauge group is G = GL(2) and use it to generate a series of exact solutions from a simple seed solution.

Cluster observations of the midaltitude cusp under strong northward interplanetary magnetic field [PDF]

open access: yes, 2008
We report on a multispacecraft cusp observation lasting more than 100 min. We determine the cusp boundary motion and reveal the effect on the cusp size of the interplanetary magnetic field (IMF) changing from southward to northward.

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 ...
