The Kadison-Singer Problem




The Kadison-Singer problem is a problem in the theory of
C*-algebras that was motivated by mathematical physics. It has been open
for over 50 years. Recently, work of Casazza lead to a resurgence of
interest in this problem, when he proved that the Kadison-Singer problem
was equivalent to the Feichtinger problem, which arose from the theory
of wavelets and signal processing. The Feichtinger problem is a more
easily stated problem in the theory of frames. In this talk I will
introduce this area, survey some of the recent progress and discuss what
I believe to be some of the more approachable unresolved special cases
and related problems.
