A COSMOLOGICAL CONSTANT WITH D4 xS1 xM5COMPACTIFICATION OF CHIRAL CLOSED STRING
-
Abstract
A cosmological constant has been derived from compactification of chiral closed-string. The (3+l)-dimensional space-time D4 has de-Sitter or anti-de-Sitter geometry. The compact space M5 is a Einstein manifold or a hyperbolic manifold. Some properties about tachyon and massless ghost have been discussed.
