Eugen Hellmann
We show that the Kisin varieties associated to simple -modules of rank are connected in the case of an arbitrary cocharacter. This proves that the connected components of th…

On the structure of some moduli spaces of finite flat group schemes
Eugen Hellmann
We consider the moduli space, in the sense of Kisin, of finite flat models of a 2-dimensional representation with values in a finite field of the absolute Galois group of a totally…
