The time-efficient DLN algorithms for the Navier-Stokes equations
Dahlquist, Liniger, and Nevanlinna proposed a two-step time-stepping scheme for systems of ordinary differential equations (ODEs) in 1983. The little-explored variable time-stepping scheme has advantages in numerical simulations for its fine properties such as unconditional G-stability and second-order accuracy.

Quyuan Lin - Between viscous and inviscid primitive equations
Abstract: The primitive equations (PE) are widely used in the study of geophysics, in particular when the aspect ratio of the domain is small, such as the ocean and atmosphere in the planetary scale. They are derived from the Navier-Stokes equations or Euler equations by taking the hydrostatic limit. The viscosity plays an important role in the properties of the PE.
