Let $(M,Z,\alpha)$ be a compact $b^m$-contact manifold, with critical set $Z$. A singular periodic orbit is an integral curve of the Reeb $b$-vector field in $M\setminus Z$ whose l…

Let $M$ be an eventually singular contact manifold, and let $Z$ denote its critical set. An orbit in $M\setminus Z$ is quasi-closed if it is either closed or its $\alpha$- and…
