Abstract:

We present a theoretical analysis of the CORSING (COmpRessed SolvING) method for the numerical approximation of partial differential equations based on compressed sensing. In particular, we show that the best $s$-term approximation of the weak solution of a PDE with respect to a system of $N$ trial functions, can be recovered via a Petrov-Galerkin approach using $m \ll N$ test functions. This recovery is guaranteed if the local $a$-coherence associated with the bilinear form and the selected trial and test bases fulfills suitable decay properties. The fundamental tool of this analysis is the restricted inf-sup property, i.e., a combination of the classical inf-sup condition and the well-known restricted isometry property of compressed sensing.
