概要
For a smooth scheme X over a perfect field of char p,
we construct an overconvergent de Rham-Witt complex
as a differential graded algebra over the ring of over-
convergent Witt-vectors. The complex is suitable to
compute the Monsky-Washnitzer cohomology if X is affine
and the rigid cohomology if X is quasiprojective.
