| Abstract: | The pricing problem of an American Barrier option was considered in a fractional Black-Scholes model under the assumption that the underlying asset price satisfies a geometric fractional Brownian motion. The approximate solution of this option was obtained by using the quadratic approximation method and partial differential equation,and some examples were provided. Finally, the numerical examples using the finite difference method were provided to verify the conclusions. |
