ar X iv : g r - qc / 0 61 20 14 v 2 8 D ec 2 00 6 Eisenhart ’ s theorem and the causal

We give a causal version of Eisenhart's geodesic characterization of classical mechanics. We emphasize the geometric, coordinate independent properties needed to express Eisenhart's theorem in light of modern studies on the Bargmann structures (lightlike dimensional reduction). The construction of the space metric, Coriolis 1-form and scalar potential through which the theorem is formulated is ...

It is shown that in the standard vacuum 5D Kaluza-Klein gravity there is a wormhole-like solution which look like a string attached to two D-branes. The asymptotical behaviour of the corresponding metric is investigated.
