By using G-Itôformula and G-expectation property, we propose Euler scheme and Milstein scheme which have order-1.0 convergence rate. And two numerical experiments including Ornstein-Uhlenbeck and Black-Scholes cases are given.展开更多

By using the G-Itôformula and the properties of G-expectation, two main theorems about Itôintegral are obtained and proved. These two theorems provide powerful help for the subsequent research on jump process.展开更多
