摘要：
LRS Bianchi type-l models have been studied in the cosmological theory based on Lyra's geometry. A new class of exact solutions has been obtained by considering a time dependent displacement field for constant deceleration parameter models of the universe. The physical behaviour of the models is examined in vacuum and in the presence of perfect fluids. (C) 2003 Elsevier B.V. All rights reserved.
