Abstract
For a perfect field of characteristic and a smooth and proper formal scheme over the ring of integers of a finite and totally ramified extension of , we propose a cohomological construction of the Breuil-Kisin modules attached to the -adic \'etale cohomology . We then prove that our proposal works when , , and the crystalline cohomology of the special fiber of is torsion-free in degrees and .
