Proper Affine Vector Fields in Bianchi Type I Space-Times
arXiv:gr-qc/0508002
Abstract
A study of Bianchi type I space-times according to its proper affine vector field is given by using holonomy and decomposability, the rank of the Rieman matrix and direct integration techinques. It is shown that the special class of the above space-times admits proper affine vector fields.
