Helmut Hofer introduced in '93 a novel technique based on holomorphic
curves to prove the Weinstein conjecture. Among the cases where these
methods apply are all contact 3-manifolds (M,ξ) with
π2(M) ≠ 0. We modify Hofer's argument to
prove the Weinstein
conjecture for some examples of higher dimensional contact manifolds.
In particular, we are able to show that the connected sum with a real
projective space always has a closed contractible Reeb orbit.
