T-Dual Cosmological Solutions of Double Field Theory II


In this paper we present cosmological solutions of double field theory in the supergravity frame and in the winding frame which are related via T-duality. In particular, we show that the solutions can be viewed without the need of complexifying the cosmological scale factor.
