A note on Howe’s oscillator semigroup. (English) Zbl 0674.47029

Analytic extensions of the metaplectic representation by integral operators of Gaussian type have been calculated in the \(L^ 2({\mathbb{R}}^ n)\) and the Bargmann-Fock realisations by Howe and Brunet-Kramer, respectively. In this paper we show that the resulting semigroups of operators are isomorphic and calculate the intertwining operator.
