Title: Long-time error growth in Strang splitting method for the nonlinear Schrödinger equation
Time & Venue: 2026年10月20日（星期二）10:00-11:00 思源楼S723
Abstract: Strang splitting is a classical second-order method for nonlinear Schrödinger equations. Its convergence order, however, does not describe how the error grows with time. Standard Gronwall arguments typically yield exponential upper bounds, whereas numerical experiments exhibit linear, quadratic, and exponential growth. This talk investigates the mechanisms behind these different behaviors for the periodic cubic nonlinear Schrödinger equation.
