چکیده انگلیسی
In the recent paper by Mark C. Ho (2014) the notion of a λ-Toeplitz operator on the Hardy space H2(T) over the one-dimensional torus T was introduced and it was shown (under the supplementary condition) that for λâT the essential spectrum of such an operator is invariant with respect to the rotation zâ¦Î»z; if in addition λ is not of finite order the essential spectrum is circular. In this paper, we generalize these results to the case when T is replaced by an arbitrary compact Abelian group whose dual is totally ordered.
