Description
T-duality has been shown to constrain the higher derivative corrections of string theory. We revisit the problem of understanding the T-duality constraints imposed on the alpha prime corrections using the language of a torsionful connection to construct O(d,d) invariant building blocks for general d-dimensional torus compactifications. This also suggests that there are in fact some hidden geometrical structures in string theory and use this to revisit the heterotic and bosonic ten-dimensional string action at order alpha prime.
