摘要
We consider the existence of Einstein-Maxwell-dilaton plus fluid systems for the case of stationary cylindrically symmetric spacetimes. An exact inhomogeneous epsilon-order solution is found, where the parameter epsilon parametrizes the non-minimally coupled electromagnetic field. Some its physical attributes are investigated and a connection with the already known Godel-type solution is given. It is shown that our solution also survives in the string-inspired charged gravity framework. We find that a magnetic field has positive influence on the chronology violation unlike the dilaton influence.
