Explicit Martingale Representations for Brownian Functionals and Applications to Option Hedging

et

référence BibTeX

Using Clark-Ocone formula, explicit martingale representations for path-dependent Brownian functionals are computed. As direct consequences, explicit martingale representations of the extrema of geometric Brownian motion and explicit hedging portfolios of path-dependent options are obtained.
