Norms of compact perturbations of operators
Norms of compact perturbations of operators
Let ,A{lt) denote the algebra of all bounded linear operators on a complex separable Hubert space.This paper is concerned with reducing the norm of a product of operators by compact perturbations of one or more of the factors.For any T in 3#($f), it is well known that the infimum, \\T\\ …
