Integral p-adic Hodge theory - announcement

Given a proper, smooth (formal) scheme over the ring of integers of C-p, we prove that if the crystalline cohomology of its special fibre is torsion-free then the p-adic etale cohomology of its generic fibre is also torsion-free. In this announcement we sketch the proof, which relies on the construction of a new cohomology theory interpolating crystalline and etale cohomology. Further details and results will be presented in the full forthcoming article.
