Math Help - Martingale representation theorem

1. Martingale representation theorem

If I have the process

$dY(t)=Y(t)(\sum_{k=1}^{m}V_{k}(t)dW_{k}(t)+d\xi(t) )$

How do I use the martingale representation to find Y?

2. Re: Martingale representation theorem

I know that $M(t)=M(0)_+\int^{t}_{0}V_{s}dW_{s}$

And the process in my original equation is $\sum_{k=1}^{m}V_{k}(t)$
