Материал из Онлайн справочника
In mathematics, infinitesimal cohomology is a cohomology theory for algebraic varieties introduced by Шаблон:Harvs. In characteristic 0 it is essentially the same as crystalline cohomology. In nonzero characteristic p Шаблон:Harvtxt showed that it is closely related to etale cohomology with mod p coefficients, a theory known to have undesirable properties.
