内容提要：
In this talk, we will talk about the high order numerical methods for ideal MHD equations. In the first part, we will review the finite difference WENO schemes for ideal MHD equations within constrained transport framework. In the second part, we talk about the development of a class of high-order positivity-preserving finite difference WENO methods, by we utilizing the maximum-principle-preserving flux limiting technique, originally designed for high-order WENO methods for scalar hyperbolic conservation laws.
