Geometry of Vegetation Pattern
One of the effects of climate change is the phenomenon of desertification, a process that occurs in semiarid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation selforganizes to sustain itself by forming largescale spatial patterns.

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

Geometry and Topology in Active and Driven Systems
The key characteristic of active matter is the motion of an emergent collection (such as a flock of birds), which is driven by the consumption of energy by its active components (i.e. individual birds).

Dual Complexes of Semistable Varieties
This thesis is comprised of three chapters covering the theme of studying semistable varieties by looking at their dual combinatorial objects.

Density functional theory is an accurate predictor for variation with geometry of barriers for reactions on metals
A semiempirical version of the specific reaction parameter approach to density functional theory (SRPDFT) has been remarkably successful at predicting dissociative chemisorption probability vs. incidence energy curves for reactions on metal surfaces. New quantum Monte Carlo (QMC) calculations on the…

Global Fields and Their Lfunctions
Artin Lfunctions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

Arithmetic of affine del Pezzo surfaces
In this thesis integral points on affine del Pezzo surfaces are studied.

A Tour of Arithmetic Geometry
Conference

Inverse Jacobian and related topics for certain superelliptic curves
To an algebraic curve C over the complex numbers one can associate a nonnegative integer g, the genus, as a measure of its complexity.

ASML Graduation Prize for mathematics student Pim Spelier – Incentive Prize for firstyear student Jorre The
Alumnus Pim Spelier is one of the two winners of the ASML Graduation prizes for mathematics students. He used a new method to solve single polynomial equations. Bachelor student Jorre The wins one of the ORTEC Incentive prizes for the best study results during the first year. On 30 November, the Royal…
