Exact monopole instantons and cosmological solutions in string theory from Abelian dimensional reduction
We compute the exact string vacuum backgrounds corresponding to the noncompact coset theory SU(2,1)/SU(2). The conformal field theory defined by the level k=4 results in a five-dimensional singular solution that factorizes in an asymptotic region as the linear dilaton solution and an S<SUP>3&l...

description |
We compute the exact string vacuum backgrounds corresponding to the noncompact coset theory SU(2,1)/SU(2). The conformal field theory defined by the level k=4 results in a five-dimensional singular solution that factorizes in an asymptotic region as the linear dilaton solution and an S<SUP>3</SUP> model. It presents two Abelian compact isometries that allow us to reinterpret it from a four-dimensional point of view as a stationary and magnetically charged space-time resembling in some aspects the Kerr-Newman solution of general relativity. The k=13/7 theory, on the other hand, describes a cosmological solution that interpolates between a singular phase at short times and an S<SUP>1</SUP>xS<SUP>2</SUP> universe after some Planckian times. |
