Finite action principle and non-singular cosmological models



In this work, an attempt is made to consider hypothetical cosmological mo­dels free from two types of singularities: divergent action and divergent sca­lar curvature. Such models form an extremely narrow subclass and look qui­te unnatural. However, our goal is to show that such cosmologies are pos­sible in principle without conflicting with current physical paradigms.
