Title: Automorphisms of Borel quotients of FDD-algebras

Abstract: Assume there exists a measurable cardinal. Using generalized groupwise Silver forcing I build a model of set theory in which every automorphism of a Borel quotient of a FDD-algebra (finite dimensional decomposition) has a *-homomorphism representation (lifting).
