arXiv:1003.0999
Abstract
We give two integrability criteria for representations of Banach--Lie algebras as skew-symmetric unbounded operators on a dense domain of a Hilbert space.
arXiv comment10 pages, minor corrections. The proof of Prop. 10 is made more elementary (the Trotter-Kato Approximation Thm is not used anymore). To appear in Journal of Functional Analysis
