singularity formation; zero thickness collapse; Euler equations; regular tube; three-dimensional incompressible flow
Summary: We define the notion of a ``regular tube'', and prove that a regular tube convected by a three-dimensional incompressible flow cannot collapse to zero thickness in finite time.
