3/9 
Time change, trace Dirichlet forms, and relation to elementary potential theory 
Tianyi Zheng 
Defined time changed process induced by additive functionals and Revuz measures. Covered local times, inverse local times, classical 2nd RayKnight theorem, construction of Dirichlet form for timechanged process. Example: RBM on a simply connected planar domain as a time change of RBM on the unit disc under conformal transformation. Mostly drawn from Chapter 5 of ChenFukushima.

Mark Cerenzia 


< < 
Introducing Mandelbrot's hypothesis and setup. 

> > 
Introducing Mandelbrot's conjecture that the Hausdorff dim of planar Brownian motion is 4/3, and setup.
