Title: Concentration inequalities for bandlimited functions


Abstract: In this talk the following problem is considered: How much of 
an integral norm of a function with compactly supported Fourier 
transform can be concentrated on a sparse subset of the real line?

The inequalities that form an answer to this question turn out to be the 
main building blocks for applications from signal processing and 
analytic number theory. I will describe some of the applications and 
will outline existing strategies (building on work of Selberg and of 
Donoho and Logan) to prove these inequalities.
