I shall present in this talk a joint result with M. Abreu, J. Kang and L. Macarini on the existence of periodic Reeb orbits. More precisely, that every non-degenerate Reeb flow on a closed contact manifold $M$ admitting a strong symplectic filling $W$ with vanishing first Chern class carries at least two geometrically distinct closed orbits provided that the positive $S1$-equivariant symplectic homology of $W$ satisfies a mild condition. We shall then provide numerous example of manifolds satisfying this “mild condition”
