This subproject of 'From Homo Economicus to Political Animal' will be on ancient analogues for modern-day “ersatz economics”, the economics of the “man in the street”.

The Feature Co-occurrence Constraint theory proposed in this dissertation provides a means to capture the development of the language learning child's segment inventory.

On 19 December 2019, Reza Eftekhar defended his thesis 'The Role of the Domestic Law of the Host State in Determining the ratione materiae Jurisdiction of Investment Treaty Tribunals: The Partial Revival of the Localisation Theory'. The doctoral research was supervised by Prof. E. de Brabandere.

In his dissertation Gabriel Paiuk explores the variable ways in which what is heard is formed. To address this, he postulates a novel concept of sound image in a post-anthropocentric context in which both mind and material artefacts are instances across which the image occurs, rather than hosts on which…

From 2 to 6 June 2014, Prof. dr. Frank den Hollander has provided 2 lectures during the workshop ‘Recent Models in Random Media’ at the Centre International de Rencontres Mathematique in Marseille (CIRM). This center facilitates workshops for mathematicians throughout the year.

Before Maria Gabriela Palacio Ludeña became a lecturer International Studies at Leiden University, she was a public administrator in Ecuador. Her whole life she had a desire to teach and eventually she wound up at Leiden University.

The centre of our Galaxy is so dark and dense that it is almost impossible to observe what is inside. By catching the rare hypervelocity stars that are ejected from it, Elena Maria Rossi aims to unveil the mysterious environment around the supermassive black hole inside. But she’ll also be solving another…

On March 12th, Jonathan Brown succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Jonathan on this great result.

Knowledge and culture subproject 3:

This book is about what happens when two people meet. Its main aim is to present an account of intersubjectivity.

The risk that conspiracy theories could incite a broad movement against the established political order is virtually non-existent. This is what researcher Jelle van Buuren of the Institute of Security and Global Affairs concluded in his PhD dissertation.

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 network brings together scholars whose work explores how contemporary frameworks of crisis produce experiences of the present, rehash or disrupt established narratives of the past, and broker specific outlooks on the future. We collaborate in studying these crisis-scapes and exploring how they…

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.

The information below concerns courses that our group teaches in Leiden. 

Research in the POD-group addresses all features of random phenomena – modelling, structuring, analysis, control, optimisation – and covers both fundamental and applied aspects.

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.

On 12 May, GTGC Deputy Coordinator Valentina Carraro presented her work during the symposium “EU Crises: Rethinking European integration theories” at Maastricht University. The symposium was organised as part of the farewell event for the retirement of Prof. Tannelie Blom.

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

This article presents two related arguments. First, the limits of doctrinal analysis cut deeper than many EU lawyers realise. Most would probably accept that legal doctrine does not determine every legal dispute, but lawyers studying EU institutional balance often still assume that it can be deduced…

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

When does it rain when air is oversaturated with moisture? How does an infection spread among the population? The problems that mathematician Professor Frank den Hollander tries to solve come from physics, chemistry and biology.

Effectiveness of an early intervention program for anxiety-prone toddlers in the Netherlands

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.

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

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.
