On the 7th and 8th of November, Radboud University and Utrecht University are jointly organising a masterclass for (Re)MA students and PhD candidates on the life and times of those lay people dependent on monasteries.

This thesis has three main parts. The first part gives an algorithm to compute Hilbert modular polynomials for ordinary abelian varieties with maximal real multiplication. Hilbert modular polynomials of a given level b give a way of finding all of the abelian varieties that are b-isogeneous to any given…

In the early universe, the dynamics of the Higgs field can give rise to many interesting phenomena.

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.

Carbohydrates, or sugars, are the most diverse and most abundant biomolecules known. However, the isolation of carbohydrate samples in sufficient amounts and purity is often impractical or even impossible, so the chemical synthesis of glycosides becomes relevant. The glycosylation reaction, in which…

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.

This thesis concerns the relation bettween the good reduction of Shimura varieties and the associated loop groups.

Gibbs measures, as used in Statistical Mechanics, have a definition that is remarkably similar to the definition ofg-measures, used in dynamical systems.

In this course, you will explore the organs involved in our food digestion and discover the common causes of abdominal and pelvic pain. The latest graphics and animations will give you new insights and understandings of this part of the body.

This course uses the lives, ideals and achievements of Theodore, Franklin, and Eleanor Roosevelt to create the idea of a Rooseveltian century. It is an invitation to think critically and historically, and it wants to give you a glimpse of what it means to be a historian at work.

Kidney transplantation is a major advance of modern medicine. This course will give you state of the art updates about what used to be an experimental, risky, and very limited treatment option more than 50 years ago and is now routinely performed in many countries worldwide.

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

Transplantation of labial salivary glands to the eyelids for patients with dry eye appears to give excellent results clinically.

I will give a general introduction to the field of molecular electronics, its history, methods and challenges. I will also introduce the subject of my investigation and provide a brief outlook to the remainder of our thesis.

Statistical distributions in LCA and converting between different representations of these distributions.

Effectiveness and Side-effects.

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.

This thesis mainly focuses on multimodal understanding and Visual Question Answering (VQA) via deep learning methods. For technical contributions, this thesis first focuses on improving multimodal fusion schemes via multi-stage vision-language interactions.

Leiden University offers a unique range of summer courses where you can broaden or deepen your knowledge or share your expertise with fellow students. The choice of academic courses is very diverse, ranging from Law, Big Data, Languages and Linguistics to Maths and Natural Sciences, Biology, Biomedical…

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

This thesis describes a study from both a theoreticaL and an experimental point of view.

Quantum hardware comes with a different computing paradigm and new ways to tackle applications. Much effort has to be put into understanding how to leverage this technology to give real-world advantages in areas of interest for industries such as combinatorial optimization or machine learning.

For many system in statistical physics the microcanonical and canonical ensemble are equivalent in the thermodynamic limit, but not for all.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

In the first part, we introduce a new condition, called toric-additivity, on a family of abelian varieties degenerating to a semi-abelian scheme over a normal crossing divisor.

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

Op 23 juni 2020 verdedigde Santy Kouwagam haar proefschrift 'How lawyers win land conflicts for corporations: Legal Strategy and its influence on the Rule of Law in Indonesia'. Het promotieonderzoek is begeleid door promotoren prof.dr. A.W. Bedner en prof.dr. C.E. von Benda-Beckmann.
