Artin L-functions 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.

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

This thesis provides explicit expressions for the density functions of absolutely continuous invariant measures for general families of interval maps, that include random maps and infinite measure transformations, not necessarily number systems.

The overarching clinical aim of this thesis was to improve pharmacological pain management by characterizing the pharmacodynamics of analgesics. This promotion has been awarded the predicate cum laude.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

Waarom spraken negentiende-eeuwse wetenschappers zo graag over toewijding, vlijt en ijver? Waarom wijdde Robert Fruin zijn oratie aan onpartijdigheid en riep Abraham Kuenen zijn studenten op tot waarheidsliefde?

Chapter 1,contains the numerical verification of the Birch and Swinnerton-Dyer conjecture for hundreds of Jacobians of hyperelliptic curves of genus 2, 3, 4 and 5.

Hij schept orde in de chaos en analyseert satellietzwermen. Tijdens zijn promotieonderzoek verdiepte wiskundige Oliver Nagy zich in willekeurige netwerken en hoe deze tot evenwicht komen. Tussendoor ontwikkelde hij ook nog even een handige tool. Deze kennis is waardevol voor onder andere berekeningen…

To an algebraic curve C over the complex numbers one can associate a non-negative integer g, the genus, as a measure of its complexity.

The unit residue group, to which the present thesis is devoted, is defined using the norm-residue symbol, which Hilbert introduced into algebraic number theory in 1897.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

Most of current public-key cryptography is considered insecure against attacks from sufficiently powerful quantum computers. Post-quantum cryptography studies methods to secure information resistant against such attacks. One proposal is isogeny-based cryptography, which bases its security on computational…

In this thesis, rational points on K3 surfaces are studied. In the first part of Chapter 1 the Brauer group and the the Brauer-Manin obstruction are introduced.

Stochastic resetting is simple enough to be approached analytically, yet modifies stochastic processes in a non-trivial way.

One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

Combinatorial games are games for two competing players, moving in a turn-by-turn fashion, in which there is no chance nor hidden information⁠. Chess, checkers and the simpler tic tac toe are well-known examples of this class of games, as well as game of go⁠.
