An upper bound on the number of e-foldings

Abstract

If the present acceleration of the universe is due to an asymptotically de Sitter universe with small cosmological constant, and the principle of Cosmological Complementarity is valid, then the number of e-foldings during inflation is bounded.

16 pages, latex. New version has extensive modifications to clarify the basic assumptions on which the bound is based and can be viewed as a response to the paper of Lowe and Marolf, correction of typos and added references
