They model the price process as a geometric Brownian motion by adding a multiple of the large traders investment to the constant drift. The majority of literature considers the case of a single large trader. [33], however, consider a continuous time financial market where the price impact - both temporary and permanent -

We can also think of the two-dimensional Brownian motion (B1 t;B 2 t) as a complex valued Brownian motion by consid-ering B1 t +iB 2 t. The paths of Brownian motion are continuous functions, but they are rather rough. With probability one, the Brownian path is not di erentiable at any point.
