What year was the original proposer of the dS/CFT correspondence of string theory born?
DS/CFT correspondence In string theory, the dS/CFT correspondence is a de Sitter space analogue of the AdS/CFT correspondence, proposed originally by Andrew Strominger. In this correspondence, the conjectured CFT boundary is in the future, and time is the emergent dimension.
Abraham Zelmanov Abraham Zelmanov (May 15, 1913 – February 2, 1987), was a prominent scientist working in the General Theory of Relativity and cosmology. He first constructed, in 1944, the complete mathematical method to calculate physical observable quantities in the General Theory of Relativity (the theory of chronometric invariants). Applying the mathematical apparatus, in the 1940s, he established the basics of the theory of inhomogeneous anisotropic universe, where he determined specific kinds of all cosmological models — scenarios of evolution — which could be theoretically conceivable for a truly inhomogeneous and anisotropic Universe in the framework of Einstein's theory.
