The Cesàro operator on weighted Bergman Fréchet and (LB)-spaces of analytic functions
Ersin Kızgut
The spectrum of the Cesàro operator is determined on the spaces which arises as intersections (resp. unions ) of Bergman spaces of order $…
The Cesàro operator on duals of smooth sequence spaces of infinite type
Ersin Kızgut
The discrete Cesàro operator is investigated in strong duals of smooth sequence spaces of infinite type. Of main interest is its spectrum, which turns out to be distin…
The Cesàro operator on smooth sequence spaces of finite type
Ersin Kızgut
The discrete Cesàro operator is investigated in the class of smooth sequence spaces of finite type. This class contains properly the power series spaces of fi…
On the existence of a factorized unbounded operator between Fréchet spaces
Ersin Kızgut, Murat Yurdakul
For locally convex spaces and , the continuous linear map is called bounded if there is a zero neighborhood of such that is bounded in . Our ma…
Remarks on bounded operators in -Köthe spaces
Ersin Kızgut, Elif Uyanık, Murat Yurdakul
For locally convex spaces and , the continuous linear map is said to be bounded if it maps zero neighborhoods of into bounded sets of . We denote $(X,Y) \…
Some stability results in projective tensor products
Ersin Kızgut, Murat Yurdakul
Let be a pair of Fréchet spaces. In this paper, we discuss whether a certain property enjoyed by both and is also satisfied by the complete tensor product $E \w…
Remarks on strictly singular operators
Ersin Kızgut, Murat Yurdakul
A continuous linear operator is called strictly singular if it cannot be invertible on any infinite dimensional closed subspace of its domain. In this note we discuss s…
