Crystals and maths
In mathematics, crystals are Cartesian sections of certain fibered categories. They were introduced by Alexander Grothendieck (1966a), who named them crystals because in some sense they are "rigid" and "grow". In particular quasicoherent crystals over the crystalline site are analogous to quasicoherent modules over a scheme. An isocrystal is a crystal up to isogeny. They are $${\displaystyle p}$$-adic analogues of -adic étale WebIn mathematics, crystalline cohomology is a Weil cohomology theory for schemes X over a base field k.Its values H n (X/W) are modules over the ring W of Witt vectors over k.It was introduced by Alexander Grothendieck (1966, 1968) and developed by Pierre Berthelot ().. Crystalline cohomology is partly inspired by the p-adic proof in Dwork (1960) of part of …
