Abstract
Let B(t), 0≤t≤∞ be a Brownian motion on (ω, F, P) with with B 0=0. Let F(t), 0≤t≤∞ be its filtration, with F(∞)=F. We construct, simple examples of probability measures P′≈P for which this filtration is not generated by the corresponding Girsanov process, but is nevertheless generated by some process which is a Brownian motion for the measure P′.
