Contractive inequalitie for Bergman spaces and multiplicative Hankel forms.

Abstract. We consider sharp inequalities for Bergman spaces of the unit disc, establishing analogues of the inequality in Carleman's proof of the isoperimet- ric inequality and of Weissler's inequality for dilations. By contractivity and a standard tensorization procedure, the unit disc in...
