MATH 519 - Stochastic Processes - FALL 2009

INFORMATION AND HOMEWORK



The course will give a comprehensive introduction to a modern topic in stochastic analysis and stochastic processes: Levy Processes and Stochastic Calculus with application to Financial Mathematics and Stochastic Differential Equations. The course is a continuation of last semester's course by A. Novikov, but that course is not a prerequisite. I am planning to begin with an overview of basic probabilty notions (e.g. martingales, stochastic process...). The lecture will cover: infinitely divisible laws, stable distributions, Levy processes, semigroups and generators of Markov processes, stochastic integration (multiple integrals), Malliavin calculus, mathematical finance, stochastic differential equations.


Literature: David Applebaum: Levy Processes and Stochastic Calculus, 2nd edition, Cambridge Studies in Advanced Mathematics 116, Cambridge University Press 2009. Price: used 54$ and up. New: 35 pounds.
In order to prepare for the class, you may download and study the basics of probability and measure theory as described in the Lecture Notes to be found at http://www.math.psu.edu/denker/517ProbabilityTheory.html
