Math-Fi seminar on 20 Sep.

2012.09.18 Tue up
  • Date: 20 Sep(Thu)
  • Place: W.W. 7th-floor
  • Time: 15:00 — 17:30


15:00 — 16:00 
  • Speaker: Jiao Ying
  • Title: Portfolio optimization with insider’s initial information
  • Abstract:
We consider an insider maximizing her expected utility with portfolio terminal wealth with information flow on the default of a counterparty.
We prove that if there is no limit for short-selling strategy, then the insider can achieve unbounded utility expectation.
So we propose suitable strategy constraint under which we study the optimization problem and compare the results with the case for a standard investor. This is a joint work with C. Hillairet.

Math-Fi seminar on 13 Sep.

2012.08.28 Tue up
  • Date: 13 Sep (Thu)
  • Place: W.W. 7th-floor

15:00 — 16:00
  • Speaker: Freddy Delbaen
  • Title: BSDE with unbounded terminal Value, Uniqueness Problem.
  • Abstract:
We consider a BSDE with convex driver that is quadratically bounded.  If the terminal value has exponential moments higher than a critical exponent, then the solution exists and is unique.  However the uniqueness problem remains open if the exponential moment only exists up to this critical exponent.  This is joint work with Ying Hu and Adrien Richou.
 
16:30 — 17:30
  • Speaker: Eva Löcherbach
  • Title: Malliavin calculus and ergodicity of stochastic system forced by degenerate noises
  • Abstract:
We first have a fast review of Malliavin calculus, mainly on the existence and smoothness of density for degenerate SDEs. Then we briefly review strong Feller property, irreducibility, ergodicity of stochastic system and Doob’s method. Finally, we shall use Malliavin calculus to prove the ergodicity of some stochastic degenerate SDEs.
