报告摘要(Abstract)：I will present some recent advances on using the scalar auxiliary variable (SAV) approach to develop highly efficient and accurate structure preserving schemes for a large class of dissipative and conservative nonlinear systems. These schemes can preserve energy dissipation/conservation as well as other global constraints, only require solving decoupled linear equations with constant coefficients at each time step, and can achieve higher-order accuracy. In particular, I will discuss applications of the SAV approach to incompressible Navier-Stokes equations.
