Mathematics of Finance

### Winter 2009

This course is an introduction to the mathematics of financial models, especially hedging and arbitrage pricing. The course begins with the development of the basic ideas of hedging and arbitrage pricing in the discrete time setting of binomial tree models. Relevant notions (conditional expectation, martingale, change of measure, martingale representation) will be introduced in this discrete setting. Continuous time models will then be covered, based on the Brownian motion process and Itô's stochastic calculus. These tools will be applied to option pricing and the Black-Scholes formula. Additional topics will be discussed, as time allows.
- We shall be using the text
*A Course in Financial Calculus* by A. Etheridge. I plan to
discuss most of the material contained in chapters 1-5 of the text.
- Lectures will be on Monday, Wednesday and Friday, from 2 pm to 2:50 pm, in APM 7421.
- Your course grade will be based on homework assignments, of which there will be about 5 or 6 assigned.
- The official prerequisite for this course is Math 180A (an upper-division Introduction to Probability course). Experience with martingales and conditional expectations is a plus, but we will develop these ideas along the way.
