In [Wic08], the second author established a local C1,α partial regularity theory for stable
branched minimal hypersurfaces of multiplicity < 3. The main regularity theorem of [Wic08] in particular im...

The newly emerging theory of compressed sensing
(CS) enables restoring a sparse signal from inadequate number of linear projections. Based on compressed sensing theory, a new algorithm of high-resolu...
