Résumé :
This work is concerned with stochastic optimal control for a
running maximum cost. A direct approach based on dynamic program-
ming techniques is studied leading to the characterization of the value
function as the unique viscosity solution of a second order Hamilton-
Jacobi-Bellman (HJB) equation with an oblique derivative boundary
condition. A general numerical scheme is proposed and a convergence
result is provided. Error estimates are obtained for the semi-Lagrangian
scheme. These results can apply to the case of lookback options in fi-
nance. Moreover, optimal control problems with maximum cost arise in
the characterization of the reachable sets for a system of controlled sto-
chastic differential equations. Some numerical simulations on examples
of reachable analysis are included to illustrate our approach.
