The reduction of the 11 dimensional supergravity action on an elliptically fibered Calabi-Yau fourfold gives rise to an N=2 supersymmetric theory in 3 dimensions which is dual to a 4 dimensional N=1 F-theory reduction. We will consider how higher derivative corrections to the 11 dimensional action modify these effective theories. Our discussion of this will include an analysis of the effective action for the Kahler moduli taking into account contributions which come from the expansion of both the 11 dimensional metric and 3 form.
