Summary: For every homogeneous Hilbertian operator space H, we construct a Hilbertian operator space X such that every infinite dimensional subquotient Y of X is completely indecomposable, and fails the Operator Approximation Property, yet H is completely finitely representable in Y. If H satisfies certain conditions, we also prove that every completely bounded map on such Y is a compact perturbation of a scalar.
Keywords: Operator spaces, homogeneous Hilbertian spaces, finite representability, Operator Approximation Property.
