Essential norm of the extensions of Stevic-Sharma operator on some spaces of analytic functions
Mostafa Hassanlou, Hussain Gissy
In this paper, we consider two extensions of Stevic-Sharma operator and find estimations for the essential norm of them from QK(p; q) and H1 into weighted Bloch spaces.

On the exponential integrability of conjugate functions
H. Gissy, S. Miihkinen, J. A. Virtanen
We relate the exponential integrability of the conjugate function to the size of the gap in the essential range of . Our main result complements a related theorem of…
