Course Description: This is the first half of a yearly sequence of graduate probability theory at the measure-theoretic level. There will be an emphasis on rigorous proofs.
In this course, we aim to cover the following main topics:

• Elements from measure theory (bare minimum which is needed to give measure-theoretic formulation of probability theory).
• Random variables, integration and independence.
• Different notion of convergences.
• Weak and strong laws of large numbers.
• Central limit theorems.
• Conditional distribution and conditional expectation.
• Other topics (depending on time).

Prerequisite: Upper division analysis: Math 5616 (or equivalent) - the students should be familier with concepts such as uniform convergence, continuity, sequences and series of numbers and functions, Riemann integral and the topology (open, closed, compact sets, etc.) of the real line. No background in measure theory will be assumed. Some familiarity with basic undergrad probability will be helpful.

Textbook (for both 8651 and 8652): Probability: Theory and Examples by Rick Durrett, Cambridge Series in Statistical and Probabilistic Mathematics, 4th Edition. Also available online.

Other recommended books:
1. Probability and Measure (3rd Edition) by Patrick Billingsley.
2. Probability with Martingales by David Williams.
3. A Modern Approach to Probability theory by Bert Fristedt and Lawrence Gray.

Homework: There will be biweekly homework assignments (around 7 in total). The lowest score will be dropped in calculating the final score. Homework are due on the corresponding deadlines in class. Late homework will not be accepted. You are allowed and even encoraged to discuss homework solutions with your friends. However, you have to write your own solutions. To get full credit, be neat and answer with reasons.

Final Exam: 4:00-6:00pm, Monday, December 17.
