Abstract of a paper by T. Figiel and W. B. Johnson
This is an announcement for the paper "The Dual Form of the Approximation Property for a Banach Space and a Subspace" by T. Figiel and W. B. Johnson. Abstract: Given a Banach space X and a subspace Y, the pair (X,Y) is said to have the approximation property (AP) provided there is a net of finite rank bounded linear operators on X all of which leave the subspace Y invariant such that the net converges uniformly on compact subsets of X to the identity operator. The main result is an easy to apply dual formulation of this property. Applications are given to three space properties; in particular, if X has the approximation property and its subspace Y is script L-infinity, then X/Y has the approximation property.
