Product Formulæ for Non-Self-Adjoint Semigroups
摘要
We start this chapter by preliminaries (Sect. 9.1), which contain a short outline of the theory of sesquilinear forms and the representation theorems about corresponding operators. They are indispensable for our analysis and construction of the product formulæ, which are based on idea of the analytic extension method that involves the analytic families (A) and (B) of m-sectorial generators.
