Prof. Franz Luef  (Berkeley)
Title: Operator algebras in time-frequency analysis

Abstract: In recent years operator algebras have found various  
applications in time-frequency analysis. In this talk I am going to  
discuss some of these developments. Concretely, I will present the  
interpretation of Gabor frames in terms of noncommutative geometry  and 
the equivalence of Feichtinger's conjecture on the  decomposition of 
frames in Hilbert spaces with the Kadison-Singer  conjecture on the 
extension of pure states.
