摘要
We prove that for every Lipschitz isomorphism f from a separable Hilbert space H to a Banach space Y with Radon-Nikodym property, there is a bounded surjective linear operator T： H → Y so that （f ＋ T）-1 （NG（f-1）） is a r-null set of H, where NG（f-1） is the set of all the points of Gateaux non-diiTerentiability of f -1.
