The aim of this seminar is to gain an understanding of the (relatively) recent work of Bhatt–Morrow–Scholze on integral \(p\)-adic Hodge theory.

## References

The primary reference, of course, is the paper of Bhatt–Morrow–Scholze listed below. Besides that, however, Bhatt and Morrow have each written additional articles that explain specific aspects of the main paper.

Bhargav Bhatt, Matthew Morrow, and Peter Scholze, Integral \(p\)-adic Hodge theory.

Bhargav Bhatt, Specializing varieties and their cohomology from characteristic \(0\) to characteristic \(p\).

Matthew Morrow, Notes on the \(\mathbf{A}_{\mathrm{inf}}\) cohomology of Integral \(p\)-adic Hodge theory.
