Abstract |
|
Bounded Hankel forms with respect to weighted norms are studied. The Nehari’s theorem about the norms of the classical Hankel forms is generalized. This is essentially a lifting theorem due to Cotlar and Sadosky. Moreover a theorem about the essential norms of Hankel forms is proved. This relates with a theorem of Adamjan, Arov and Krein in the special case and gives a new lifting theorem which has applications to weighted norm inequalities, and the F. and M. Riesz theorem. |
