As a consequence, when the symbol function $f$ is holomorphic, we characterize bounded and compact Hankel operators $H\overline{_f}$ between weighted Bergman spaces. In particular, this resolves two questions left open in [7, 12].35 p.application/pdfeng(c) Indiana University Mathematics Journal, 2016Operadors linealsTeoria d'operadorsFuncions de diverses variables complexesLinear operatorsOperator theoryFunctions of several complex variablesinfo:eu-repo/semantics/article6589122017-02-16info:eu-repo/semantics/openAccess
