Minimal Distance Upper Bounds for the Perturbation of Least Squares Problems in Hilbert Spaces
Mathematics and Natural Sciences
Let X and Y be Hilbert spaces, and let T : X → Y be a bounded linear operator with closed range. In this paper, we present an optimal perturbation result on the least squares solutions to the operator equation Tx = y under the most general condition.
