 Then ("T""h")∗(γ) is equivalent to "γ" with Radon–Nikodym derivative

where

denotes the Paley–Wiener integral.The Cameron–Martin formula is valid only for translations by elements of the dense subspace "i"("H") ⊆ "E", called Cameron–Martin space, and not by arbitrary elements of "E".If the Cameron–Martin formula did hold for arbitrary translations, it would contradict the following result
