Maximum Principle for General Controlled Systems Driven by Fractional Brownian Motions [PDF]

open access: yes, 2012
We obtain a maximum principle for stochastic control problem of general controlled stochastic differential systems driven by fractional Brownian motions (of Hurst parameter $H>1/2$). This maximum principle specifies a system of equations that the optimal
