Summary
The Bianchi-type cosmological models have been studied in Lyra’s geometry for a law of variation of Hubble’s parameter presented by Berman (1983) that yields constant deceleration parameter models of the universe. All the models have a singular origin (t = 0) and evolve with time. The gauge function \(t) is an arbitrary function of time.
