Steady Nonintegrable High-Dimensional Fluids

We consider the existence of steady incompressible fluids (solutions to the Euler equations) on Riemannian manifolds of dimensions three and higher. We demonstrate that, as in the case of the ABC fields in dimension three, there exist chaotic Beltrami fields – nonsingular eigenfields of the curl operator – in higher dimensions. We give an explicit set of analytic examples on a non-Euclidean five-torus T ⁵. We also detail a plug construction for inserting chaotic vortices into a Beltrami field. These constructions employ contact-topological techniques.
