Ramification and moduli spaces of finite flat models

Annales de l’institut Fourier

Similarity:

We determine the type of the zeta functions and the range of the dimensions of the moduli spaces of finite flat models of two-dimensional local Galois representations over finite fields. This gives a generalization of Raynaud’s theorem on the uniqueness of finite flat models in low ramifications.

Normality and non-normality of group compactifications in simple projective spaces

Paolo Bravi, Jacopo Gandini, Andrea Maffei, Alessandro Ruzzi (2011)

Annales de l’institut Fourier

Similarity:

Given an irreducible representation V of a complex simply connected semisimple algebraic group G we consider the closure X of the image of G in ( End ( V ) ) . We determine for which V the variety X is normal and for which V is smooth.
