Steve Dilworth, Daniel Freeman, Denka Kuzarova, Edward Odell (co-chair), and Thomas Schlumprecht (co-chair) are organizing a Concentration Week on "Greedy Algorithms in Banach spaces and Compressed Sensing" for the week of July 18-22. When encoding or reconstructing a vector using an iterative algorithm, a natural approach is to take the best or biggest approximation at each iteration. Such techniques are referred to as greedy algorithms. The theory of compressed sensing is concerned with encoding and reconstructing vectors which are sparsely represented with respect to a given basis. Kevin Ford will present a series of talks on deterministic construction of matrices with the restrictive isometry property. There will be a second series of talks devoted to greedy algorithms and bases. The home page for this Concentration Week is at http://www.math.utexas.edu/users/freeman/greedy11/index.html

Florent Baudier (chair), Bill Johnson, Piotr Nowak, and Bunyamin Sari are organizing a Concentration Week on "Non-Linear Geometry of Banach Spaces, Geometric Group Theory, and Differentiability" for the week of August 1-5. The program will include an introductory course by Mark Sapir on coarse embeddings and their applications to geometric group theory, and a series of lectures by Gilles Godefroy on the recent work of the late Nigel Kalton on the coarse classification of Banach spaces.

We expect to be able to cover housing for most participants from support the National Science Foundation has provided for the Workshop. When you ask Cara to book your room, please tell her if you are requesting support. Minorities, women, graduate students, and young researchers are especially encouraged to apply.
