Ha, maybe I express it too simple.
Yes, in that case, we have to reconstruct the binomial tree ...
Is my previous solution right?Perhaps,in this case,PDE method is better than Tree method,a PDE method for time varying volatility is similar with the PDE method for constant volatility.If sigma(t) is a more complicated function of t,PDE maybe the best choice.
