For homogeneous polynomials
$G_1,\ldots ,G_k$ over a finite field, their Dwork complex is defined by Adolphson and Sperber, based on Dwork’s theory. In this article, we will construct an explicit cochain map from the Dwork complex of
$G_1,\ldots ,G_k$ to the Monsky–Washnitzer complex associated with some affine bundle over the complement
$\mathbb {P}^n\setminus X_G$ of the common zero
$X_G$ of
$G_1,\ldots ,G_k$, which computes the rigid cohomology of
$\mathbb {P}^n\setminus X_G$. We verify that this cochain map realizes the rigid cohomology of
$\mathbb {P}^n\setminus X_G$ as a direct summand of the Dwork cohomology of
$G_1,\ldots ,G_k$. We also verify that the comparison map is compatible with the Frobenius and the Dwork operator defined on both complexes, respectively. Consequently, we extend Katz’s comparison results in [19] for projective hypersurface complements to arbitrary projective complements.
