Spectrum of weighted composition operators. Part XI. The essential spectra of some weighted composition operators on the disc algebra
Arkady Kitover, Mehmet Orhon
We obtain a complete description of semi-Fredholm spectra of operators of the form acting on the disc algebra in the case when is either elliptic or doub…

Spectrum of Weighted Composition Operators. Part IX. The spectrum and essential spectra of some weighted composition operators on uniform algebras
Arkady Kitover, Mehmet Orhon
We obtain some results about the spectrum and the upper semi-Fredholm spectrum of weighted composition operators on uniform algebras, assuming that the corresponding map maps the S…
