Abstract

We define a family of associative products (Formula Presented) on a space S of real analytic functions on (Formula Presented) that are contained in the range of the heat transform for all times t > 0. Extending results in Bauer (J Funct Anal 256:3107–3142, 2009), Coburn (J Funct Anal 161:509–525, 1999; Proc Am Math Soc 129(11):3331–3338, 2007) we show that this product leads to composition formulas of in general unbounded Berezin–Toeplitz operators (Formula Presented) denotes the Segal–Bargmann space over (Formula Presented) with respect to the semi-classical parameter s > 0. In the special case of operators with polynomial symbols or for products of just two operators such formulas previously have been obtained in Bauer (J Funct Anal 256:3107–3142, 2009), Coburn (Proc Am Math Soc 129(11):3331–3338, 2007), respectively. Finally we give an example of a bounded real analytic function h on (Formula Presented) such that (Formula Presented) cannot be expressed in form of a Toeplitz operator (Formula Presented) where g fulfills a certain growth condition at infinity.
