摘要:
This paper deals with the numerical solution of the time-dependent, three-dimensional Heston-Cox-Ingersoll-Ross PDE, with all correlations nonzero, for the fair pricing of European call options. We apply a finite difference discretization on non-uniform spatial grids and then numerically solve the semi-discrete system in time by using an Alternating Direction Implicit scheme. We show that this leads to a highly efficient and stable numerical solution method.
