On the local well-posedness for the relativistic Euler equations for a liquid body

Daniel Ginsberg, Hans Lindblad

We prove a local existence theorem for the free boundary problem for a relativistic fluid in a fixed spacetime. Our proof involves an a priori estimate which only requires control…

On quasisymmetric plasma equilibria sustained by small force

Peter Constantin, Theodore D. Drivas, Daniel Ginsberg

We construct smooth, non-symmetric plasma equilibria which possess closed, nested flux surfaces and solve the magnetohydrostatic (steady three-dimensional incompressible Euler) equ…

Flexibility and rigidity in steady fluid motion

Peter Constantin, Theodore D. Drivas, Daniel Ginsberg

Flexibility and rigidity properties of steady (time-independent) solutions of the Euler, Boussinesq and Magnetohydrostatic equations are investigated. Specifically, certain Liouvil…

Local well-posedness for the motion of a compressible, self-gravitating liquid with free surface boundary

Daniel Ginsberg, Hans Lindblad, Chenyun Luo

We establish the local well-posedness for the free boundary problem for the compressible Euler equations describing the motion of liquid under the influence of Newtonian self-gravi…

On the lifespan of three-dimensional gravity water waves with vorticity

Daniel Ginsberg

We prove a long-term regularity result for three-dimensional gravity water waves with small initial data but nonzero initial vorticity. We consider solutions whose vorticity vanish…

A priori estimates for a relativistic liquid with free surface boundary

Daniel Ginsberg

We prove energy estimates for a relativistic free liquid body with sufficiently small fluid velocity in a general Einstein spacetime. These estimates control Sobolev norms of the f…
