High-order adaptive space-discretizations for the Black–Scholes equation

چکیده
In this paper we develop a high-order adaptive finite difference space-discretization for the Black–Scholes (B–S) equation. The final condition is discontinuous in the first derivative yielding that the effective rate of convergence is two, both for low-order and high-order standard finite difference (FD) schemes. To obtain a sixth-order scheme we use an extra grid in a limited spaceand time-domain. The new sixth-order method is called FD6G2. The FD6G2-method is combined with spaceand time-adaptivity to further enhance the method. To obtain solutions of high accuracy in several dimensions the adaptive FD6G2-method is superior to both standard and adaptive second-order FD-methods.

Adaptive Finite Element Approximation of the Black - Scholes Equation Based on Residual - Type a Posteriori Error Estimators
For the pricing of options on equity shares, the Black-Scholes equation has become an indispensable tool for agents on the financial market. Under the assumption that the value of the underlying share evolves in time according to a stochastic differential equation and some further assumptions on the financial market, the equation can be derived by an application of Itô’s calculus. It represents...
