Abstract
We address the issue of slow roll in string theory models of inflation. Using a Kähler transformation and results from the D3–D7 model, we show why we expect flat directions to be present and slow roll to be possible in general. We connect with earlier discussions of shift symmetry for T6/Z2 and K3 × T2/Z2 compactifications. We also collect various contributions to the inflationary potential and discuss their importance for slow roll. We include a few simple checks of the form of the Kähler potential on T6/Z2 using T-duality.
