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.

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.

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

Ice, the solid state of water, plays an important role on our planet as well as the entire universe.Despite the fact that an individual water molecule has a very simple structure, its chemical bonding in the solid phase can be surprisingly complex.

This thesis consists of three chapters, the first two of which concern division points of elements of the multiplicative group of a number field.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.

This thesis consists of three chapters. Each chapter is on a different subject. However, all three chapters address issues that arise in counting arithmetically interesting objects.

'Ik stond vorig jaar in Nature, ik was genomineerd voor de facultaire prijs voor docent van het jaar; het liet mijn kinderen allemaal koud. Maar als je simulaties in The Big Bang Theory verschijnen, dan is het ineens wat anders! ’ aldus Huib van Langevelde.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

Vincenzo Vitelli is per 1 juni 215 benoemd tot hoogleraar Theory of Condensed Matter.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

This thesis develops a method for direction dependent calibration of the ionosphere in radio interferometric data.

The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

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

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

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

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

Professor Edwin Bakker, directeur van het Centrum voor Terrorisme & Contraterrorisme heeft zijn nieuwe boek getiteld 'Terrorism and Counterterrorism Studies: Comparing Theory and Practice' bij Leiden University Press uitgebracht.

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.
