Abstract:We introduce and study the asymptotically commuting bounded approximation property of Banach spaces. This property is, e.g., enjoyed by any dual space with the bounded approximation property. The principal result is the following: if a Banach space X has the asymptotically λ-commuting bounded approximation property, then X is saturated with locally λ-complemented separable subspaces enjoying the λ-commuting bounded approximation property.
Keywords:Banach spaces   The asymptotically commuting bounded approximation property   Approximation properties defined by operator ideals   Extension operators   (Locally) complemented subspaces
