摘要：

We present a comparative study about the dynamics of geodesic orbits in static cylindrically symmetric vacuum spacetimes with and without a cosmological constant.. In particular, we analyze the orbital stability of the Lambda = 0 case with respect to the introduction of arbitrarily small values of vertical bar Lambda vertical bar and single out the cases where bounded orbits become unbounded.
