Abstract

The study of vortex lines in a inviscid, incompressible Euler fluid dates back to the times of Lord Kelvin. Vortex lines are highly idealised mathematical objects which at first sight do not seem relevant to vortices and turbulence in real fluids. In this article I show that superfluid vortices are good physical realizations of these classical mathematical objects, and provide us with a convenient context to investigate topological aspects of turbulence. © 2007 Birkhaueser.
