Stochastic integration 2009-2010 (code ST409018) ContentsStochastic calculus is an indispensable tool in modern financial mathematics. In this course we present this mathematical theory and apply it to the problem of pricing and hedging of financial derivatives. We treat the following topics from martingale theory and stochastic calculus: martingales in discrete and continuous time, construction and properties of the stochastic integral, Ito's formula, Girsanov's theorem, stochastic differential equations. As an application, we explain how stochastic differential equations are typically used to model financial markets and we discuss the problem of the pricing of derivatives such as stock options.PrerequisitesMeasure theory, stochastic processes at the level of the course Measure Theoretic ProbabilityLiteratureRecommended background reading: I. Karatzas and S.E. Shreve, Brownian motions and stochastic calculus and D. Revuz and M. Yor, Continuous martingales and Brownian motion. The contents of the course are described in the lecture notes (which are based on these books). Updated version of the lecture notes by February 6. This mainly concerns a small reorganization, the BDG inequallty has been moved from Section 11 to Section 7.
Companion courseStudents are recommended to take also the course on Stochastic Processes, see the Spring Courses of the Dutch Master Program in Mathematics.Follow up coursesCourses that heavily rely on stochastic calculus are Financial Stochastics and Control of Stochastic Systems in Continuous Time.LecturerP.J.C. SpreijHomeworkStrict deadlines: the lecture after you have been given the assignment, although serious excuses will always be accepted.ScheduleSpring semester: usually Thursdays, 15:15-17:00 (note the changed hours), Room P.015B. First lecture on 4 February 2010, 15:00-18:00. From April 1 on, there will be three hours of class every week, 15:15 - 18:00; last class on April 22; exception: Friday 16 April 14:00 - 16:45 in room P.018, instead of Thursday 15. The schedule below will be adjusted during the remaining period.ExaminationThe final grade is a combination of the results of the take home assignments and the oral exam. To take the oral exam, you make an appointment for a date that suits your own agenda (and mine as well). If it happens that you'd like to postpone the appointment, just inform me that you want so. This is never a problem! The only important matter is that you take the exam, when you feel ready for it. To plan your own agenda, please note that I am not always in Amsterdam. For the time being I am not available in the periods April 28 - May 7, May 20 - June 2, June 16 - June 19, June 28 - July 3. As soon as more is known, it will appear here.Programme(last modified: )
