Crystal (mathematics)
In mathematics, crystals are Cartesian sections of certain fibered categories. They were introduced by Alexander Grothendieck , 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. A Dieudonné crystal is a crystal with Verschiebung and Frobenius maps. An F-crystal is a structure in semilinear algebra somewhat related to crystals.
