Özet

It is shown that the spacetimes described by Gödel-type metrics with both flat and non-flat backgrounds and with constant uk always have CTCs or CNCs. The geodesic curves of these spacetimes are characterized by a lower dimensional Lorentz force equation for a charged point particle in the relevant Riemannian background. An explicit example is given for which timelike and null geodesics can never be closed. © 2008 World Scientific Publishing Co. Pte. Ltd.
