The volume represents the proceedings of the 21st International
Conference on Operator Theory, held in Timisoara, Romania, in 2006. Three of
the included papers are surveys on active areas of research:

- renormalization group in algebraic quantum field theory
- composition operators on Hardy-Orlicz and Banach-Orlicz spaces
- operator ideals on Hilbert spaces

The remaining fourteen papers contain original research on a wide variety of topics:

- single operator theory
- Banach algebras
- \(C^*\)–algebras
- von Neumann algebras
- Hilbert and Banach modules
- differential and integral operators
- noncommutative probability
- spectral theory

A publication of the Theta Foundation. Distributed worldwide, except in Romania, by the AMS.
