DESCRIPTION: This course provides an introduction to the mathematics of some financial models. The aim is to provide students with an introduction to some basic probabilistic models of finance and associated mathematical machinery. The course focusses largely on financial derivatives and related mathematics.
The course begins with the development of the basic ideas of hedging and pricing of derivatives in the discrete (i.e., discrete time and discrete state) setting of binomial tree models. The famous Black-Scholes option pricing formula is derived as a limit from these models. Then a general discrete finite market model is introduced, and the fundamental theorems of asset pricing are proved in this setting. Tools from probability such as conditional expectation, filtration, (super)martingale, equivalent martingale measure, and martingale representation are all introduced and used in this discrete setting.
This course requires a solid background in probability, preferably at the level of the undergraduate probability course Math 180A at UCSD, or at a bare minimum Math 183. It also uses a certain amount of geometric linear algebra, so it is a good idea to review background from Math 20F.
The graduate course, Math 294, which has a similar title, is at a more advanced level and has much more emphasis on continuous time models which use measure theory.
PREREQUISITES: Math 20D, Math 20F or Math 31AH, and Math 180A or Math 183.
TEXT: No specific text is required.
Some summary notes will be provided to accompany the course.

HOMEWORK: Homework will generally be given weekly. Homework will be due by Friday, noon in the TA homework box. Click here to go to the homework.
EXAMS: There will be one midterm (in class) exam and a final exam. In class exam: Wed, Feb 15, 2012. Final exam: Wed, March 21, 2012, 7-10pm.
The final on Wednesday, March 21 will be from 7pm to 10pm in PH103. The final will be an overall test of the material covered in the lectures, reading and homework for the whole quarter. Please bring your student ID, a blue book or two, and pens/pencils to write with. You may bring a single 8.5"x11" sheet of paper with writing on both sides of it to the exam. No books or other notes are allowed. You may bring a calculator. Make sure to justify your answers (credit will not be given for "inspired'' answers). Remember that part of each problem is to set it up and to arrive at the answer by a progression of logical steps. Please start each problem on a new page, write legibly, and put your name and section number on your blue book.
Review session: Sunday, March 18, 3pm, Calculus Lab (B402A).
