Let A0be an A-algebra and let B0:= B AA0, then B 0=A ˘=B0 B 1 B=A as B0-modules Proof. The morphism d Id A0: B0! 1 B=A B 0satis es the universal property of 1 B0=A0 since for every A 0-module M and every derivation f : B0!M we have a derivation B!Mgiven by b!f(b) 1) 2M, and by the universal property of 1 B=A there is a morphism f^:

WebOct 3, 2024 · The stacky approach was originated by Bhatt and Lurie. (But the possible mistakes in my talk are mine.) Let X be a scheme over F_p. Many years ago Grothendieck and Berthelot defined the notion of crystal on X; moreover, they defined the notion of crystalline cohomology of a crystal. I will give several equivalent definitions of a stack X ... WebAn -crystal is called nondegenerate if there exists an integer a map such that . Remark 60.26.3. Let be an -crystal as in Definition 60.26.2. In the literature the nondegeneracy condition is often part of the definition of an -crystal. Moreover, often it is also assumed that .
