In this paper, we search for accelerating power-law and ekpyrotic solutions in heterotic string theory with NS-NS fluxes compactified on half-flat and generalized half-flat manifolds. We restrict our searches to the STZ sector of the theory. We also considered linear order $\alpha'$ corrections for the half-flat case. The power-law solutions that we find are neither accelerating nor ekpyrotic in any of the models.

From the scalar potential ([ref]) we get the following $α⃗$ vectors: α⃗_1 = {-√(6),-√(2),-√(2/3)}, α⃗_2={√(2/3),-√(2),-√(6)}, α⃗_3 = {-√(2/3),-√(2),-√(6)}, α⃗_4={-√(6),-√(2),-√(6)}.As outlined above and also in [ref] we need to find the $P$ values for the largest common set of $α⃗$ vectors that are mutually affine.

However, in the heterotic setting there is a dearth of sources and fluxes, and an alternative to turning on fluxes is to replace the compactification Calabi-Yau manifold by SU(3) manifolds known as half-flat mirror manifolds, which bear close resemblance to the original Calabi-Yau manifolds [ref] .
