Proof methods for robust low-rank matrix recovery
Tim Fuchs, David Gross, Peter Jung +3
Low-rank matrix recovery problems arise naturally as mathematical formulations of various inverse problems, such as matrix completion, blind deconvolution, and phase retrieval. Ove…
Rigidity for perimeter inequality under spherical symmetrisation
Filippo Cagnetti, Matteo Perugini, Dominik Stöger
Necessary and sufficient conditions for rigidity of the perimeter inequality under spherical symmetrisation are given. That is, a characterisation for the uniqueness (up to orthogo…
Complex phase retrieval from subgaussian measurements
Felix Krahmer, Dominik Stöger
Phase retrieval refers to the problem of reconstructing an unknown vector or from measurements of the form $y_i = \big\vert \lang…
On the convex geometry of blind deconvolution and matrix completion
Felix Krahmer, Dominik Stöger
Low-rank matrix recovery from structured measurements has been a topic of intense study in the last decade and many important problems like matrix completion and blind deconvolutio…
