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 toquasicoherent modules over a scheme.
