A remark on crystalline cohomology [PDF]
Abstract We propose a new approach to crystalline cohomology based on the observation that one can lift smooth algebras uniquely “up to coherent homotopy.”

On the crystalline cohomology of Deligne–Lusztig varieties
Let $X\to Y^0$ be an abelian prime-to-$p$ Galois covering of smooth schemes over a perfect field $k$ of characteristic $p>0$. Let $Y$ be a smooth compactification of $Y^0$ such that $Y-Y^0$ is a normal crossings divisor on $Y$. We describe a logarithmic $F$-crystal on $Y$ whose rational crystalline cohomology is the rigid cohomology of $X$, in ...

Specialization of crystalline cohomology
Let \(f: X\to S\) be a proper smooth morphism of schemes over a perfect field of characteristic \(p\). Using the theory of convergent isocrystals, it is shown that the Newton polygons of the \({\mathbb{Q}}\otimes H^ i_{cris}(X_ s/W(s))\) (the relative crystalline cohomology of a fiber) are constant along the strata of a suitable stratification of A and

Etale and crystalline companions, I [PDF]
Let $X$ be a smooth scheme over a finite field of characteristic $p$. Consider the coefficient objects of locally constant rank on $X$ in $\ell$-adic Weil cohomology: these are lisse Weil sheaves in \'etale cohomology when $\ell \neq p$, and ...

Dieudonné theory via cohomology of classifying stacks
We prove that if G is a finite flat group scheme of p-power rank over a perfect field of characteristic p, then the second crystalline cohomology of its classifying stack $H^2_{\text {crys}}(BG)$ recovers the Dieudonné module of G.

Generalized Lieb-Schultz-Mattis theorem on bosonic symmetry protected topological phases
We propose and prove a family of generalized Lieb-Schultz-Mattis (LSM) theorems for symmetry protected topological (SPT) phases on boson/spin models in any dimensions. The "conventional" LSM theorem, applicable to e.g. any translation invariant system

For symmorphic crystalline interacting gapped systems we derive a classification under adiabatic evolution. This classification is complete for non-degenerate ground states.

SERRE WEIGHTS AND BREUIL’S LATTICE CONJECTURE IN DIMENSION THREE
We prove in generic situations that the lattice in a tame type induced by the completed cohomology of a $U(3)$-arithmetic manifold is purely local, that is, only depends on the Galois representation at places above $p$. This is a generalization to $\text{
