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…

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.

The main topic of this PhD thesis is the Arakelov ray class group of a number field, an algebraic object that contains both the ideal class group structure and the unit group structure.

De 21e eeuw is getuige van een revolutie in ons begrip van rationale punten op oppervlakken en hoger-dimensionale variëteiten, en het is binnen dit vakgebied dat dit project zich bevindt.

In this thesis we examine certain phenomena in symplectic topology which are related to the theory of isolated singularities.

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…

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

In this thesis, we explore a Hochschild homology and cohomology-like notion for logarithmic schemes.

Er worden verschillende activiteiten georganiseerd in het kader van het gastschrijverschap. Vast onderdeel is de Albert Verweylezing, die Giphart op donderdagavond 21 november 2024 zal houden. Op 11 september wordt Giphart geïnterviewd door Sander Bax en Rick Honings.

In this thesis we study products of linear error correcting codes.

Op 10 november 2021 verdedigde Carmel van Niekerk-Jacobs het proefschrift 'Realising the right to reproduce with assistance in South Africa'. Het promotieonderzoek is begeleid door prof.dr. J.J. Sloth-Nielsen en prof.dr. T. Liefaard.

One of the main challenges in the development of an effective anti-cancer vaccine is the generation of an adequate and directed cellular immune response.

Autophagy is a fundamental degradative process, maintaining cellular homeostasis and functions in host defense against intracellular pathogens, including mycobacteria and Salmonella.

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

Mining time series is a machine learning subfield that focuses on a particular data structure, where variables are measured over (short or long) periods of time.

Fundamental research in the ALgebra, Geometry And Number Theory

This PhD thesis concerns the topic of arithmetic geometry. We address three different questions and each of the questions in some way is about counting how big some set is or can be.

This dissertation presents new cryptographic protocols, which can be divided into two families.

Arithmetic geometry concerns the number-theoretic properties of geometric objects defined by polynomials. Mathematicians are interested in the rational solutions to these geometric objects.

This thesis studies the geometry of representation varieties and character stacks. These are spaces parametrizing the representations of a finitely generated group, typically the fundamental group of a compact manifold, into an algebraic group G.

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.
