The Varied Landscape of Operator Theory

The volume contains the proceedings of the 24th International Conference on Operator Theory, held in Timisoara from July 2-7, 2012. Leading experts in the field have contributed with several survey papers, covering the following subjects: amenability on coset spaces large orbits of operators and operator semigroups approximation numbers of composition operators commutators in the algebra of bounded operators on a Hilbert space interplay between algebraic groups, Lie algebras, and operator ideals free group factors and Hecke operators The remaining papers contain original research on different topics: single operator theory, C*-algebras, operators on functino spaces, quantum semigroups, moment problems, and semigroups on ordered Banach spaces.
