제목 : Introduction to the operator splitting method
초록 : In this talk, we introduce the operator splitting method for some nonlinear equations. For any time, the method gives an approximation solution depending only on initial data for the nonlinear equation. In this argument, we divide the nonlinear equation into computable parts and consist of the approximation solution by composing these computable parts. This method is widely used for numerical computation. However, it remains a very fundamental question to converge between the approximation with the original solution. In this talk, we study some convergence results which applying harmonic analysis tools to numerical analysis. This work is joint with Hyung Jun Choi and Woocheol Choi.
