On the Perturbation of the Reduced Minimum Modulus of Bounded Linear Operators
Mathematics and Natural Sciences
Let X and Y be two Banach spaces, and let T:X→Y be a bounded linear operator. We study the perturbation problem of the reduced minimum modulus of T, and in particular we correct a mistake in a recent paper.
