Improved Boundary Error Control for BSDEs using Convolution-FFT
Analysis
This paper builds upon the Convolution-FFT (CFFT) method for solving Backward Stochastic Differential Equations (BSDEs), a technique relevant to financial modeling, particularly option pricing. The core contribution lies in refining the CFFT approach to mitigate boundary errors, a common challenge in numerical methods. The authors modify the damping and shifting schemes, crucial steps in the CFFT method, to improve accuracy and convergence. This is significant because it enhances the reliability of option valuation models that rely on BSDEs.
