The Generalized Steltjes and Fourier Transforms of Certain Spaces of Generalized Functions

Inspired of Roumieu and Beurling definitions, we defined spaces of ultradifferentiable functions of rapid descents in Lp spaces which shown to be closed with respect to the classical Stieltjes transform.

THE Ip QUANTUM INVARIANT OF PERIODIC 3-MANIFOLDS

We use the periodicity of the Jones polynomial introduced first by Murasugi to give a congruence that relates the invariant of a periodic 3-manifold and the corresponding invariant of its orbit 3-manifold.

GENERALIZED HANKEL-TYPE TRANSFORMATION FOR A CLASS OF TEMPERED ULTRADISTRIBUTIONS OF ROUMIEU-TYPE

As the third in a series of papers the present paper aims at investigating a theory supporting Hankel-type transformation on certain spaces of generalized functions.

On Nil – Semi Clean Rings

In this paper, the notions of semi-idempotent elements and nil-semiclean elements are introduced. We show that, if a ring R is a nil-semi clean ring, then the Jacobson radical, J(R), of R is nil.
