Around the Van Daele–Schmüdgen Theorem
For a {bounded} non-negative self-adjoint operator acting in a complex, infinite-dimensional, separable Hilbert space H and possessing a dense range R we propose a new... -
Balancing Sparsity and Rank Constraints in Quadratic Basis Pursuit
We investigate the methods that simultaneously enforce sparsity and low-rank structure in a matrix as often employed for sparse phase retrieval problems or phase... -
