Integral, differential and multiplication operators on generalized Fock spaces
Tesfa Mengestie, Sei-Ichiro Ueki
Volterra companion integral and multiplication operators with holomorphic symbols are studied for a large class of generalized Fock spaces on the complex plane $\CC$. The weights d…
Essential norm of the differential operator
Tesfa Mengestie
This paper is a follow-up contribution to our work [10] where we studied some spectral properties of the differential operator acting between generalized Fock spaces $\mathcal{…
Spectral properties of Volterra-type integral operators on Fock--Sobolev spaces
Tesfa Mengestie
We study some spectral properties of Volterra-type integral operators and with holomorphic symbol on the Fock--Sobolev spaces . We showed that…
On the spectrum of Volterra-type integral operators on Fock--Sobolev spaces
Tesfa Mengestie
We determine the spectrum of the Voltterra-type integral operators on the growth type Fock--Sobolev spaces . We also characterized the bounded and c…
A note on the differential operator on generalized Fock spaces
Tesfa Mengestie
It has long been known that the differential operator represents a typical examples of unbounded operators in many Banach spaces including the classical Fock spaces, the Fock--…
Volterra type integral and composition operators on model spaces
Tesfa Mengestie
We study some mapping properties of Volterra type integral operators and composition operators on model spaces. We also discuss and give out a couple of interesting open problems i…
