   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis summarizes and gives the background to some accompanying papers dealing with the following problems.Some cosmological models, e.g. that of Gödel, indicate that there is a connection between rotation and the existence of causality violating closed time-like curves. READ MORE
