Efficient Proximal Mapping Computation for Unitarily Invariant Low-Rank Inducing Norms

Low-rank inducing unitarily invariant norms have been introduced to convexify problems with low-rank/sparsity constraint. They are the convex envelope of a unitary invariant norm and the indicator function of an upper bounding rank constraint.

On Approximation Problems With Zero-Trace Matrices

, 1994
In this paper we consider some approximation problems in the linear space of complex matrices with respect to unitarily invariant norms. We deal with special cases of approximation of a matrix by zero-trace matrices.
