The volume represents the proceedings of the conference "Operator Algebras and Mathematical Physics 3", held in Bucharest, Romania, in August 2005. It contains eight refereed papers on the following topics:

• holomorphic representations of Jacobi algebras
• groupoid \(C^*\)-algebras
• the reduced \(C^*\)-algebra of the Thompson group \(F\)
• classical low-energy scattering for a two-body system
• compact quantum groups
• Schrödinger operators and the Fermi golden rule
• boundary topological invariants in some physical systems
• index and homology of pseudodifferential operators on manifolds with boundary

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

Readership

Graduate students and research mathematicians interested in analysis.
