Parent event:
Seminar on Algebra, Geometry and Physics We will discuss the recently suggested definition of prismatic cohomology that unifies several integral cohomology theories in p-adic geometry. We briefly start with an introduction of prisms as generalization of perfectoid rings, and then describe available constructions of a prismatic site:
1) a variant of the complex $\Delta_{R/A}$$ (2016);
2) construction via topological Hochschild homology (2018).
It requires as input a highly non-trivial calculation from homotopy theory
