Abstract

We consider the dynamics of a fluid thread near pinch-off, in the limit that inertial effects can be neglected. There exists an infinite hierarchy of similarity solutions corresponding to pinch-off. Only one of the similarity solutions (the "ground state") is stable, all other solutions are linearly unstable to perturbationsthus cannot be observed. Eigenvalues and eigenfunctions are calculated analytically.
