Let R denote the annulus $\{z: \frac{1}{2} < |z| < 1\}$ and let π be a holomorphic universal covering map from the unit disk onto R. It is shown that if π is a function of an inner function ω, that is ...
Sufficient conditions are found for the existence of nontrivial invariant subspaces for Toeplitz operators with piecewise continuous symbols. The results are obtained by estimating the norm of the ...
Fock spaces serve as a fundamental framework in both mathematical analysis and quantum theory, providing a rich setting for the study of entire functions equipped with Gaussian weights. In operator ...
