Abstract

Assuming that all infinitesimal Killing vectors integrate to form a group of finite isometries, cosmological compactification of a fifth dimension is discussed. It requires a positive cosmological constant, while supporting both the big-bang singularity and the open character of ordinary space. The constancy of the fine-structure constant is correlated with the smallness of the cosmological constant.
