Families of trianguline representations and finite slope spaces
Eugen Hellmann
We apply the theory of families of (phi,Gamma)-modules to trianguline families as defined by Chenevier. This yields a new definition of Kisin's finite slope subspace as well as hig…

Connectedness of Kisin varieties for GL_2
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…
