Rigid cohomology is a theory which to varieties $X$ over a field $k$ of characteristic $p$ assigns cohomology vector spaces over a mixed characteristic local field $K$ with residue characteristic $p$ (e.g. $K={\mathbb Q}_p$ if $k={\mathbb F}_p$). If $X$ is smooth and proper then rigid cohomology coincides with crystalline cohomology (tensored with $K$). I want to sketch the construction of this theory.
