报告题目：Structure-preserving Gauss methods for the NLS equation

报告摘要：We construct high-order structure-preserving Gauss methods for the nonlinear Schrödinger (NLS) equation, namely L2 -conservative methods satisfying a discrete analogue of the energy (Hamiltonian) conservation of the equation. We also discuss efficient linearizations of the new methods and their conservation properties. Our approach is based on the scalar auxiliary variable (SAV) reformulation of the NLS equation.
