** Textbook:**

Brownian motion-- an introduction to stochastic processes.
By Rene L. Schilling and Lothar Partzsch (2012)

**Reference Books: **

Continuous martingales and Brownian motion. By Daniel Revuz and Marc Yor (1991)

Brownian motion. By Yuval Peres and Peter Morters (2010)

**Course Description:**

As the most important stochastic process, Brownian motion appears as
intersection of three fundamental classes of processes: It is a martingale, a
Gaussian process and a Markov process. Since observed by physicists,
Brownian motion has been in the center of the investigation
for both mathematicians and the people
in many other disciplines. Its fascinating link to the partial differential
equations and harmonic analysis symbols the modern day of probability.
As the scaling limit of the random walks,
Brownian motion serves a bridge between analysis and some hard problems
of discrete structure.
This course aims to provide a systematic account for the sample properties
of Brownian motions.
The course is the continuation of Math 623 of the last semester. The main
topics in this semester include Ito and other types of stochstic calculus,
Cameron-Martin formula, Brownian fractal and Brownian local times.

**Grading policy:**
