- Cosmological Models of Universe with Variable Deceleration Parameter in Lyra´s Manifold J. P. Shahi Chandra Bhan Singh Anirudh Pradhan Física, Astronomía y Matemáticas Cosmology FRW universe Lyra geometry FRW models of the universe have been studied in the cosmological theory based on Lyras manifold. Anew class of exact solutions has been obtained by considering a time dependent displacement field for variabledeceleration parameter from which three models of the universe are derived (i) exponential (ii) polynomial and(iii) sinusoidal form respectively. The behaviour of these models of the universe are also discussed. Finallysome possibilities of further problems and their investigations have been pointed out. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436620 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4A Vol.36
