comment Measure change in a bond option problem
@ Jase : I have to appologize I misread your last equation last time. It is equal to 1, only conditionally to $\mathcal{F}_{T_0}$, or alternatively if you take expectation of it, as $B(t,T)=e^{-\int_t^T f(s,t)ds}=E_\beta[e^{-\int_t^T r(s)ds}]=E_\beta[\frac{\beta(t)}{\beta(T)}]$. So your last equation (at t=0) is equal to $\frac{e^{-\int_0^{T_0} r(s)ds}}{E_\beta[e^{-\int_0^{T_0} r(s)ds}]}$. The fact that this is a correct measure change is a theorem, a version of which can be found in Brigo and Mercurio's book "Interest Rate Models Theory and Practice". Regards

comment How to show that this weak scheme is a cubature scheme?
@ vanguard2k : Yes it is, I think I know now what to prove but I am just too lazy to try to prove it. But if you are willing to do it, I would be delighted to read your attempt. As an indication about what is needed is to prove that moments of the Ninomiya-Victoir scheme matches the moments ot the stochastic iterative (stratanovitch)-integrals. Best regards
