Cylindrically symmetric spinning Brans-Dicke space-times with closed timelike curves
We present here three new exact solutions of Brans–Dicke theory for a stationary geometry with cylindrical symmetry in the presence of matter in rigid rotation with . All the solutions have eternal closed timelike curves in some region of space–time which has a size that depends on ω. Moreover, two...

| Sumario: | We present here three new exact solutions of Brans–Dicke theory for a stationary geometry with cylindrical symmetry in the presence of matter in rigid rotation with . All the solutions have eternal closed timelike curves in some region of space–time which has a size that depends on ω. Moreover, two of them do not go over a solution of general relativity in the limit ω→∞. |
