The celebrated Ito formula for the n-dimensional Brownian motion Xt and for u ∈ C2(Rn ) runs as follows: (0.1) In § 6 of this paper we extend this to the case where u is any element of the Sobolev space H1R(n ) and accordingly Δu is a tempered distribution which is not even a signed measure in general. As a consequence the second term of the right hand side of (0.1) may not be of bounded variation in t.
