The Monsky-Washnitz​er site
Dingxin Zhang, Mathematics Department, Harvard University,
Rigid cohomology defined by Berthelot agrees with the formal cohomology defined Monsky and Washnitzer for smooth affine varieties. Motivated by this, mimicking the convergent theory of Ogus, we define a site using weakly completed algebras. We show a certain sheaf cohomology of this site agrees with Berthelot's rigid cohomology.
