Construct α′ corrected or loop corrected solutions without curvature singularities

Abstract For the bosonic gravi-dilaton system, we provide systematical approaches to construct non-perturbative string cosmological solutions without curvature singularities, which can match the perturbative solution to any order in α′ expansion. When higher order α′ corrections are calculated, they...
