Chronometric Invariants

Abraham Zelmanov

Abstract

This book was written in 1944 by Abraham Zelmanov (1913-1987), a prominent scientist working in General Relativity and cosmology. Herein he constructs the theory of physical observable quantities in General Relativity (chronometric invariants), and applies it to determine the whole range of cosmological models which could be theoretically conceivable within the framework of Einstein's theory.
