Generalised rank-constrained approximations of Hilbert-Schmidt operators on separable Hilbert spaces and applications

G Carere, HC Lie - arXiv preprint arXiv:2408.05104, 2024 - arxiv.org
In this work we solve, for given bounded operators $ B, C $ and Hilbert--Schmidt operator $
M $ acting on potentially infinite-dimensional separable Hilbert spaces, the reduced rank …
