Mathematical Finance/Financial Engineering Seminar
Tuesday, December 8, 2009 - 3:00pm
1 hour (actually 50 minutes)
We focus on time inhomogeneous local volatility models, the cornerstone of projection methods of higher dimensional models, and show how to use the heat kernel expansion to obtain new and, in some sense optimal, expansions of the implied volatility in the time to maturity variable. This is joint work with Jim Gatheral, Elton Hsu, Cheng Ouyang and Tai-Ho Wang.
