Lyra's Geometry and Cosmology: A Review

Abstract

The Lyra's geometry, which is a generalization of Weyl's geometry (removing the defect of non‐integrability of length transfer) and the gravitational theory and cosmology based on this geometry have been reviewed. Further, cosmological models with both constant and time dependent displacement field have been discussed. Some of these models solve the singularity, entropy and horizon problems. Finally some possibilities of further problems and their investigations have been pointed out. Copyright © 1993 WILEY‐VCH Verlag GmbH & Co. KGaA
