Abstract
A unified treatment of Friedmann-Lemaître-Robertson-Walker models is given within the context of Lyra's manifold, which is a modification of Riemannian geometry, and comparisons are made with corresponding models in the latter geometry. The asymptotic behaviour of the models for small and largeR is discussed.
