Hankel operators and the moment problem
In this talk, we consider Hankel operators, associated with a complex valued function which is square integrable with respect to a given measure, in a Hilbert space of meromorphic functions related to a moment sequence . We investigate the boundedness and compactness of such operators in connection with the growth and the regularity of the sequence .
