Math 562: Theory of Probability II (Fall 2021)
SYLLABUS COMPASS2G DISCUSSION BOARD
This is the second half of the basic graduate course in probability theory. The goal of this course is to understand the basic theory of stochastic calculus. We will cover the following topics:
- Brownian motion;
- Continuous Time Matingales;
- Markov processes;
- Stochastic Integrals;
- Ito's formula;
- Representation of Martingales;
- Girsanov theorem and
- Stochastic Differential Equations.

Prerequisite | Math 540 Real Analysis I - we will review measure theory topics as needed. Math 541 is also nice to have, but not necessary. Math 561 Probability Theory I - you should be willing to spend time and effort on this background material if necessary. Here is the lecture note from last semester. |
Grading Policy |
Scribe notes: 10% of the course grade. Scribe the notes from 1 (or 2) lectures using the latex template with complete details. Biweekly Homework (Due Thursday 9:30am via compass): 50% of the course grade. You are encouraged to work together on the homework, but I ask that you write up your own solutions and turn them in separately. There will be few problems assigned; emphasis will be placed on clear, concise, and coherent writing. Final Exam (TBA): 40%. Take home final exam due TBA, by COMPASS2G. |
