On affine Deligne-Lusztig varieties for GLn
(2005)
In the first part of this thesis we study the global structure of moduli spaces of quasi-isogenies of p-divisible groups introduced by Rapoport and Zink. We determine their dimensions and their sets of connected components ...
The delta invariant in Arakelov geometry
(2016-05-24)
In this thesis we study Faltings' delta invariant of compact and connected Riemann surfaces.
This invariant plays a crucial role in Arakelov theory of arithmetic surfaces. For example, it appears in the arithmetic ...

Construction of a Rapoport-Zink space for split GU(1, 1) in the ramified 2-adic case
(2016-07-06)
Let F be a finite extension over the field of 2-adic numbers. In this paper, we construct a Rapoport-Zink-space for the split unitary group in two variables over a ramified quadratic extension of F. For this, we first ...
Moduli spaces of K3 surfaces and cubic fourfolds
(2019-11-14)
This thesis is concerned with the Hodge-theoretic relation between polarized K3 surfaces of degree d and special cubic fourfolds of discriminant d, as introduced by Hassett.
For half of the d, K3 surfaces associated ......

On moduli spaces of Riemann surfaces: new generators in their unstable homology and the homotopy type of their harmonic compactification
(2018-07-10)
By M_g(m,n) we denote the moduli space of conformal structures on an oriented compact cobordism S_g(m,n) of genus g greater or equal 0 and with m+n greater or equal 0 enumerated, parametrized boundary components of which ...
