In this paper, we study the matrix denoising model Y = S + X, where S is a low rank deterministic signal matrix and X is a random noise matrix, and both are M × n. In the scenario that M and n are ...

Two weeks ago, a modest-looking paper was uploaded to the arXiv preprint server with the unassuming title On the invariant subspace problem in Hilbert spaces. The paper is just 13 pages long and its ...

Let $\mathscr{L}$ be the von Neumann algebra crossed product determined by a finite von Neumann algebra $M$ and a trace preserving $^\ast$-automorphism $\alpha$ of $M ...
