DESCRIPTION:Title: <a href="https://researchseminars.org/talk/POINTS/43/">
 Prismatic approach to Fontaine's C_crys conjecture</a>\nby Haoyang Guo (MP
 IM) as part of POINTS - Peking Online International Number Theory Seminar\
 n\n\nAbstract\nGiven a smooth proper scheme over a \\(p\\)-adic ring of in
 tegers\, Fontaine's \\(C_{\\mathrm{crys}}\\) conjecture says that the éta
 le cohomology of its generic fiber is isomorphic to the crystalline cohomo
 logy of its special fiber\, after base changing them to the crystalline pe
 riod ring. In this talk\, we give a prismatic proof of the conjecture\, fo
 r general coefficients\, in the relative setting\, and allowing ramified b
 ase rings. This is a joint work with Emanuel Reinecke.\n\nLink: https://zo
