10.4.3 Can you answer these questions?

10.4.3.1 How can I set up and simulate an OrnsteinUhlenbeck process that depends on the proportional deviations from the steady state?
10.4.3.2 Solve matrix of ODEs using NDSolve
10.4.3.3 Make the ```*``` operation the Kronecker product by default for Kets?

I'm trying to set up a stochastic differential equation and run numerical simulations for the following process: 
$$\frac{dV_t}{V_t}=\left[M+\gamma\left(M-\left(\frac{V_t}{V_{t-1}}-1\right)\right)\...

So given two "Ket" objects, 
 u = Ket[{-1/2}]; 
d = Ket[{1/2}]; 
 
Is there a way to define multiplication,  * , so that by ...
