"Geometry of null geodesics in spacetimes of Goedel type" |
Abstract _ |
The structure of a light cone in spacetimes of Goedel type is studied. We derive the intrinsic cone metric,calculate the rotation coefficients of the light ray congrruence forming the cone and detrmine the local differential invariants up to second order. |
