Hi All,

We'll have our 3rd and final Boeing lecture for the quarter next Thursday,
Nov. 20 (details below). Interested faculty / staff should please sign up on
this google docs page
meet with the speaker.

*Stochastic Perron’s method for Hamilton-Jacobi-Bellman equations*

*Erhan Bayraktar, University of Michigan*
Thursday, November 20th, 4pm.
Smith Hall room 205

*Abstract:* We show that the value function of a stochastic control problem
is the unique solution of the associated Hamilton-Jacobi-Bellman (HJB)
equation, completely avoiding the proof of the so-called dynamic
programming principle (DPP). Using Stochastic Perron’s method we construct
a super-solution lying below the value function and a sub-solution
dominating it. A comparison argument easily closes the proof. The program
has the precise meaning of verification for viscosity-solutions, obtaining
the DPP as a conclusion. We will also discuss the effectiveness of this
method in analyzing the robust feedback-type optimal control problems.
