The initial value problem for Einstein ~field equations with positive cosmological constant is analysed where data are prescribed at past conformalinfinity. It is found that the data on past conformalinfinityaregiven,up to arbitrary conformal rescalings, by a freely specifybleRiemannian metric and a
Present paper is a continuation of a discussion given by R. Coquereaux and A. Grossmann (Ann. PhJx N. Y. 143 (1982), 296) on analytic solutions of spatially closed Friedman universes with cosmological constant and radiation pressure. Our purpose is to find such solutions in the case of opened univer
