Deligne--Illusie Classes as Arithmetic Kodaira--Spencer Classes

Taylor Dupuy, David Zureick-Brown

Faltings showed that "arithmetic Kodaira--Spencer classes" satisfying a certain compatibility axiom cannot exist. By modifying his definitions slightly, we show that the Deligne--I…

Total $p$ -differentials on schemes over $Z / p^{2}$

Taylor Dupuy, Eric Katz, Joseph Rabinoff +1

For a scheme $X$ defined over the length $2$ $p$ -typical Witt vectors $W_{2} (k)$ of a characteristic $p$ field, we introduce total $p$ -differentials which interpolate between Frobeni…
