On Power-Bounded Operators in Finite von
✍ Gilles Cassier; Thierry Fack 📂 Article 📅 1996 🏛 Elsevier Science 🌐 English ⚖ 717 KB

It is proved that any power-bounded operator of class C 1, } in a finite von Neumann algebra is conjugate to a unitary. This solves a conjecture stated by I. Kovacs in 1970. An important ingredient of the proof is the study of completely positive projections on some operator space.
