This is then interpreted geometrically as the survival of a face of the cross-polytope under projection. The chapter ends by pointing out the analogy with the recovery of low-rank matrices.

In the latter case, this is first done via an estimate of the restricted isometry constants and then directly through the null space property. Finally, a close relation between the restricted isometry property and the Johnson–Lindenstrauss lemma is uncovered.

The Scandal Breaks, April 1902,m samples, uniform sparse recovery is also proved to be possible via a variety of algorithms. This is derived via establishing the restricted isometry property for the associated random sampling matrix—the random partial Fourier matrix is a particular case. Finally, a connection to the ..-problem is pointed out.
