P-adic cohomology

In mathematics, p-adic cohomology means a cohomology theory for varieties of characteristic p whose values are modules over a ring of p-adic integers. Examples (in roughly historical order) include:


 * Serre's Witt vector cohomology
 * Monsky–Washnitzer cohomology
 * Infinitesimal cohomology
 * Crystalline cohomology
 * Rigid cohomology
