Kernels of Arithmetic Jet Spaces and Frobenius Morphism

Rajat Kumar Mishra, Arnab Saha

For any $I ¨ $ -formal group scheme $G$ , the Frobenius morphism between arithmetic jet spaces restricts to generalized kernels of the projection map. Using the functorial properties o…

Differential Characters and $D$ -Group Schemes

Rajat Kumar Mishra, Arnab Saha

Let $K$ be a field of characteristic zero with a fixed derivation $\partial$ on it. In the case when $A$ is an abelian scheme, Buium considered the group scheme $K (A)$ which is the…
