Hormander multiplier theorem

WebFor scalar-valued multipliers, this improves the theorem of Girardi and Weis (J. Funct. Anal., 2003), who required similar assumptions for derivatives up to the order n/r +1, wherer ≤ min(t,q)isaFourier-type of X. However, the present method does not apply to operator-valued multipliers, which are also covered by the Girardi–Weis theorem. 1 ... WebIn this paper we characterize Hankel operatorsH f andH f on the Bergman spaces of bounded symmetric domains which are in the Schatten p-class for 2≤p<∞ and f inL 2 using a Jordan algebra characterization of bounded symmetric domains and properties of the Bergman metric.
