p-torsion etale cohomology and de Rham cohohomology. How to read arithmetic from geometry.
Abstract:
Classical comparison theorem established the isomorphism between singular cohomology and de Rham cohomology for smooth manifolds. The p-adic analogy aims to compare p-adic etale cohomology to de Rham cohomology for projective smooth schemes. In this talk, I will review and explain p-torsion version of such comparison and discuss how prismatic cohomology, recently invented by Bhatt-Scholze, can help to promote such p-torsion comparison. This is joint work with Shizhang Li.
