A counterexample to the singular Weinstein conjecture
Josep Fontana-McNally, Eva Miranda, Cédric Oms +1
In this article, we study the dynamical properties of Reeb vector fields on b-contact manifolds. We show that in dimension 3, the number of so-called singular periodic orbits can b…

From 2N to infinitely many escape orbits
Josep Fontana-McNally, Eva Miranda, Cédric Oms +1
In this short note, we prove that singular Reeb vector fields associated with generic -contact forms have either (at least) or an infinite number of escape orbits, where $N…
