Topics in metric geometry, combinatorial geometry, extremal combinatorics and additive combinatorics
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 $f_1,f_2,\dots,f_n\colon X\to X$ is a \emph{contractive family} if there exists $\lambda<1$ such that for any $x,y\in X$ we have $d(f_i(x),f_i(y))\leq\lambda ...

Extremal combinatorics in generalized Kneser graphs
This thesis focuses on the interplay of extremal combinatorics and finite geometry. Combinatorics is concerned with discrete (and usually finite) objects. Extremal combinatorics studies how large or how small a collection of finite objects can be under certain restrictions. Those objects can be sets, graphs, vectors, etc.

Continuous optimisation in extremal combinatoricst
In this thesis we explore instances in which tools from continuous optimisation can be used to solve problems in extremal graph and hypergraph theory. We begin by introducing a generalised notion of hypergraph Lagrangian and use tools from the theory of nonlinear optimisation to explore some of its properties.

on certain problems in extremal and additive combinatorics [PDF]
This thesis consists of five chapters. The first chapter serves as an introduction, presenting the four problems studied in this thesis, and the results obtained. Each subsequent chapter then treats a separate problem. The second chapter is about the existence of partial isomorphisms (i.e.
