Brownian motion and the distance to a submanifold
... 3 Local Time In this section we show how the distance function relates to the local time of Brownian motion on a hypersurface. Since the boundaries of regular domains are included as exam- ples, this could ...

On the Lifetime of a Conditioned Brownian Motion
... first case, as Jordan curves are still Jordan curves and the images of the points w j still lie between the images of s and t (but in reverse order), and the image of A now lies in the bounded ...

The fractal geometry of Brownian motion
... In the following we will state as a bounded quantifier statement that this will hold for any cover and that such a cover always exists, a seemingly trivial point in the standard case, but not as obvious in the ...

A Dynamic Cournot Model with Brownian Motion
... Abstract In this paper we develop a stochastic version of a dynamic Cournot model. The model is dynamic because firms are slow to adjust output in response to changes in their economic environment. The model is ...
