HOMEWORK.

Assignment 1: Problems 1*, 2*, 3*, 4, 5* of Chapter 1. Due Friday, October 12, noon.
Hint for uniform integrability question in problem 2: recall that the Poisson process at time n is a sum of n i.i.d. random variables with finite mean and variance and so the central limit theorem applies.

Assignment 5: Problems 1, 4*, 5* from Chapter 10. Problems 3, 4 from Chapter 7 (this chapter features local time and Tanaka's formula which were mentioned when we covered an example of an SDE with a weak but no strong solution. You will probably have to read some more in Chapter 7 to do the problems from that Chapter.) Due Friday, December 7, noon. The following exercise is a good one to try after the lectures are complete: Chapter 9, Exercise 4. (No need to hand it in.)
