μ-Hankel operators on Hilbert spaces
Adolf Mirotin
Ekaterina Kuzmenkova
Abstract. A class of operators is introduced (\(\mu\)-Hankel operators, \(\mu\) is a complex parameter), which generalizes the class of Hankel operators. Criteria for boundedness, compactness, nuclearity, and finite dimensionality are obtained for operators of this class, and for the case \(|\mu| = 1\) their description in the Hardy space is given. Integral representations of \(\mu\)-Hankel operators on the unit disk and on the Semi-Axis are also considered.
Keywords: Hankel operator, \(\mu\)-Hankel operator, Hardy space, integral representation, nuclear operator, integral operator.
