  • Instabilities in asymptotically AdS spacetimes 

    Dold, Dominic Nicolas (2018-04-28)
    In recent years, more and more efforts have been expended on the study of $n$-dimensional asymptotically anti-de Sitter spacetimes $(\mathcal{M},g)$ as solutions to the Einstein vacuum equations \begin{align*} \mathrm{ ...
  • Topics in metric geometry, combinatorial geometry, extremal combinatorics and additive combinatorics 

    Milicevic, Luka (2018-03-01)
    In this thesis, we consider several combinatorial topics, belonging to the areas appearing in the thesis title. Given a non-empty complete metric space $(X,d)$, a family of $n$ continuous maps $f_1,f_2,\dots,f_n\colon X\to ...
  • Semisimple filtrations of tilting modules for algebraic groups 

    Hazi, Amit (2018-02-07)
    Let $G$ be a reductive algebraic group over an algebraically closed field $k$ of characteristic $p > 0$. The indecomposable tilting modules $\{T(\lambda)\}$ for $G$, which are labeled by highest weight, form an important ...
  • Tilings and other combinatorial results 

    Gruslys, Vytautas
    In this dissertation we treat three tiling problems and three problems in combinatorial geometry, extremal graph theory and sparse Ramsey theory. We first consider tilings of $\mathbb{Z}^n$. In this setting a tile $T$ ...
