Cohomology of operator algebras and quantum dynamical semigroups.

Research output: Contribution to journalJournal articleResearchpeer-review

A certain cohomoloical group is shown to vanish, and this implies that the generator of a uniformly bounded semi group of completely positive mappings on a von Neumann algebra has a simple form.
