Abstract:

Following Davie’s example of a Banach space failing the approximation property (1973), we show how to construct a Banach space $E$ which is asymptotically Hilbertian and fails the approximation property. Moreover, the space $E$ is shown to be a subspace of a space with an unconditional basis which is “almost” a weak Hilbert space and which can be written as the direct sum of two subspaces all of whose subspaces have the approximation property.
