**Course description**: First semester in an annual sequence of Probability Theory, aimed primarily for Ph.D. students. Topics include laws of large numbers, weak convergence, central limit theorems, conditional expectation, martingales and Markov chains.

**Prerequisites**: A first course in probability, familiarity with Lebesgue integral, strong analysis level.

**Textbooks**: Our reference text will be Probability Theory, by S.R.S. Varadhan.

**Homework**: Every Tuesday for the next Tuesday.

**Grading**: problem sets (50%) and final (50%).
