Abstract
This paper studies the boundedness and compactness of the coefficient multiplier operators between various Bergman spaces Ap and Hardy spaces Hq. Some new characterizations of the multipliers between the spaces with exponents 1 or 2 are derived which, in particular, imply a Bergman space analogue of the PaleyRudin Theorem on sparse sequences. Hardy and Bergman spaces are shown to be linked using mixednorm spaces, and this linkage is used to improve a known result on (A p ,A 2), 1<p<2.
Compact (H 1,H 2) and (A 1,A 2) multipliers are characterized. The essential norms and spectra of some multiplier operators are computed. It is shown that for p>1 there exist bounded noncompact multiplier operators from
Ap to Aq if and only if p≤q.
