The conformal symplectic Weinstein conjecture for rational exact lcs structures

Let MM be a closed manifold of dimension at least 44, and let (λ,α)(\lambda,\alpha) be an exact locally conformally symplectic structure, with α\alpha a rational Lee form. Define the vanishing distribution

Vλ(p)={vTpMdλ(v,)=0}\mathcal{V}_{\lambda}(p)=\{v\in T_pM\mid d\lambda(v,\cdot)=0\}

and the cone CλVλC_{\lambda}\subset\mathcal{V}_{\lambda} by

Cλ(p)={vVλ(p)λ(v)>0}.C_{\lambda}(p)=\{v\in\mathcal{V}_{\lambda}(p)\mid\lambda(v)>0\}.

A Reeb curve is a smooth map o:S1Mo:S^1\to M satisfying o˙(t)Cλ(o(t))\dot o(t)\in C_{\lambda}(o(t)) for every tt. Conformal symplectic Weinstein conjecture. There is a Reeb curve for (M,λ,α)(M,\lambda,\alpha). This is presented as the basic conformal symplectic analogue of the Weinstein conjecture; the source does not state a resolution.
