A characterization of steady Euler flows

Plus d'infos...

Résumé : I will show how to characterize those non-singular volume-preserving
vector fields on a closed manifold that are steady solutions to the
Euler equation for some Riemannian metric. Given a vector field, the
existence of such a metric depends on the existence of a limit to the
precision with which the asymptotic cycles can be approximated by
certain classes of loops. This is joint work with Daniel Peralta-Salas
and Ana Rechtman.
