A study of an inhomogeneous Bianchi-I model in Lyra geometry. (English) Zbl 0997.83101

Summary: The inhomogeneous Bianchi-I model based on Lyra’s geometry has been studied in the cosmological theory in the presence of a massless inhomogeneous scalar field whose potential has a flat part. The field equations are solved using separation of variables and it is shown that one of the time part of the field equations are solvable for any arbitrary other cosmic scale function. Solutions for a particular form of cosmic scale (time part) is presented.
