Core-EP pre-order of Hilbert space operators

, 2018
A new binary relation associated with the core-EP inverse is presented and studied on the corresponding subset of all generalized Drazin invertible bounded linear Hilbert space operators.

Operators commuting with complex symmetric weighted composition operators on H 2

Concrete Operators
In this article, we initially study when an anti-linear Toeplitz operator is in the commutant of a composition operator. Primarily, we investigate weighted composition operators Wg,ψ{W}_{g,\psi } commuting with complex symmetric weighted composition ...

$S$-Ultralinear algebra in the space of tempered distributions

, 2001
The aim of this paper is to introduce some new concepts that provide the space of tempered distributions with others "linear" structures in addition to its natural structure of linear vector space.
