Abstract

In this short note, we prove that singular Reeb vector fields associated with generic bb-contact forms have either (at least) 2N2N or an infinite number of escape orbits, where NN denotes the number of connected components of the critical set.

16 pages, for Alain Chenciner on his 2N-birthday. The article has undergone substantial improvement incorporating stronger results and introducing a novel count of escape orbits with multiplicity
