The Numerical Solution of Fractional Black‐Scholes‐Schrodinger Equation Using the RBFs Method

open access: yesAdvances in Mathematical Physics, Volume 2020, Issue 1, 2020., 2020
In this paper, radial basis functions (RBFs) method was used to solve a fractional Black‐Scholes‐Schrodinger equation in an option pricing of financial problems. The RBFs method is applied in discretizing a spatial derivative process. The approximation of time fractional derivative is interpreted in the Caputo’s sense by a simple quadrature formula ...
