Area integral functions and $H^{\8}$ functional calculus for sectorial operators on Hilbert spaces

Functional Analysis 2012-07-06 v1

Abstract

Area integral functions are introduced for sectorial operators on Hilbert spaces. We establish the equivalence relationship between the square and area integral functions. This immediately extends McIntosh/Yagi's results on H\8H^{\8} functional calculus of sectorial operators on Hilbert spaces to the case when the square functions are replaced by the area integral functions.
