Knowledge extraction in the quantum random-oracle model
The aim of this thesis is to present novel techniques for proving cryptographic schemes secure against quantum adversaries. Most results are within the context of an idealized model called the ‘quantum random-oracle model’.

Leer ze rekenen
Samen met taal en lezen vormt rekenen het fundament onder het curriculum van de basisschool. Rekenen is een taal apart die leerlingen zich moeten eigen maken, namelijk de taal van getallen, hoeveelheden en patronen. Uit internationaal vergelijkingsonderzoek blijkt dat Nederland relatief weinig sterke…

Decompositions in algebra
We show that Kirchhoff ’s law of conservation holds for non-commutative graph flows if and only if the graph is planar. We generalize the theory of (Euclidean) lattices to infinite dimension and consider the ring of algebraic integers as such a lattice.

Inverse electron demand Diels-Alder pyridazine elimination: synthetic tools for chemical immunology
The inverse electron demand Diels-Alder (IEDDA) pyridazine elimination emerged in 2013 as a new bioorthogonal reaction and constitutes a prime example of what is now known as dissociative bioorthogonal chemistry. The research described in this Thesis aims to develop synthetic strategies which enable…
