摘要：

This paper investigates space-times which admit an r-dimensional Lie algebra of homothetic vector fields at least one of which is proer homothetic. The situation is resolved completely if r ≥ 6 and some general results are given when r ≤ 5. Some applications to the study of affine vector fields in space-times are also given and the maximum dimension of this latter algebra is computed and corrects an earlier error. © 1990 Plenum Publishing Corporation.
