This week I am in Seville, Spain, for a conference in harmonic analysis and related topics. My talk is titled “the uniform uncertainty principle and compressed sensing“. The content of this talk overlaps substantially with my Ostrowski lecture on the same topic; the slides I prepared for the Seville lecture can be found here.
[Update, Dec 6: Some people have asked about my other lecture given in Seville, on structure and randomness in the prime numbers. This lecture is largely equivalent to the one posted here.]
