Abstract

Let H-1, H-2 be two Hilbert spaces, and let T : H-1 --> H-2 be a bounded linear operator with closed range. We present some representations of the perturbation for the Moore-Penrose inverse in Hilbert spaces for the case that the perturbation does not change the range or the null space of the operator.
