Abstract

We discuss the cosmological constant problem, at the minisuperspace level, within the framework of the so-called normalized general relativity. We prove that the Universe cannot be closed, and reassure that the accompanying cosmological constant Λ generically vanishes, at least classically. The theory does allow, however, for a special class of Λ≠0 solutions which are associated with static closed Einstein universe and with Eddington-Lemaître universe.
