Lagrangian time-analyticity for the Euler equations in a Sobolev domain
Juhi Jang, Igor Kukavica, Linfeng Li
Assuming only Sobolev regularity of the domain, we prove time-analyticity of Lagrangian trajectories for solutions of the Euler equations.

Nonradial stability of expanding Goldreich-Weber stars
Mahir HadžiÄ, Juhi Jang, King Ming Lam
Goldreich-Weber solutions constitute a finite-parameter of expanding and collapsing solutions to the mass-critical Euler-Poisson system. Two subclasses of this family correspond to…
