Closed Models,lysis. In this Chapter we shall discuss the qualitative properties of the positive-curvature FRW models and the Kantowski-Sachs models with a barotropic fluid and a non-interacting scalar field with an exponential potential [96].

Introduction,al cosmology involves the study of the early- and late- time behaviour of more general classes of cosmological models as well as the detailed investigation of special exact cosmological solutions with symmetries such as the spatially homogeneous and isotropic models with a Robertson-Walker (RW) geom

Multiple Scalar Fields,7] . There are a variety of inflationary models which include scalar fields [291], and in scalar field models with an exponential potential [372] the universe inflates at a power-law rate, .(.) ∞ .., where . > 1 [249]. As we have seen, all ever-expanding scalar field models with an exponential poten

Scalar Tensor Theories of Gravity,string theory (see [188] and references therein) . The first scalar-tensor theories to appear (with . = .. ) were due to Jordan [205, 206], Fierz [146] and Brans and Dicke [60] and the most general scalar-tensor theories were formulated by Bergmann [40], Nordtvedt [289] and Wagoner [356] . The obser
