Hankel operators on generalized Bergman-Hardy spaces


Abstract


We study Hankel operators H<sub>f</sub>:H_2→ H<sub>2</sub> on a class of spaces H<sub>2</sub> of analytic functions which includes, among many other examples, the Hardy space and the Bergman spaces obn the unit disk as well as the Fock space on ℂ. We derive compactness conditions for H<sub>f</sub> and describe the essential spectrum of H<sub>f</sub><sup>*</sup>H<sub>f</sub>. Moreover we investigate Schatten class Hankel operators. The main objects of study are those Hankel operators H<sub>f</sub> which admit a sequence of vector-valued trigonometric polynomials f<sub>j</sub> with(Error rendering LaTeX formula).
