The research programme Probability Theory focuses on probability theory and on operations research.

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

For the legal science theme Empirical Legal Studies, Leiden has chosen the topic ‘markets, behaviour, and the regulatory role of the law’ as its starting point to advance empirical legal research.

ELS@Leiden provides a platform that brings together legal scholars and social scientists to collaboratively explore legally relevant questions related to market regulation.

Starting this academic year (2016-2017) Maartje van der Woude, Professor of Sociology of Law at the Van Vollenhoven Institute will organize the Leiden Socio-Legal Series (LSLS).

The Dutch child protection system

The research of the Algebra, Geometry and Number Theory cluster tries to bridge the gap between abstract theory and the world of algorithms and applications.

The Death of Archaeological Theory, edited by John Bintliff and Mark Pearce, addresses the provocative subject of whether it is time to discount the burden of somewhat dogmatic theory and ideology that has built up over the last 25 years.

Interaction between Legal Systems acknowledges that law-making and law enforcement are increasingly taking place on various levels: in a global context, in EU context, on a national level and in a private law framework. These levels influence each other, sometimes directly, on the basis of a hierarchical…

This book presents concrete solutions for managing the legal risks distorting the development of various areas of EU law. It pursues an innovative and effective approach to identify legal risks, their causes at the EU level and their impacts on the functioning of the Union and its Member States. It…

Developing a method to simplify polynomials in complex curves

Majorana meets a mermaid

Sentencing is becoming increasingly complex for the courts. Legal scholars and criminologists from Leiden document the process of sentencing in the Netherlands. They use this knowledge to advise legislators and those who implement this legislation on how to make sentencing more consistent and effect…

The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

The master’s specialisation Algebra, Geometry and Number Theory at Leiden University is aimed at students who wish to acquire a profound knowledge of one of the areas within pure mathematics. There is a strong theme dealing with algebra and number theory as well as a strong theme dealing with topology…

Edited by linguists Jenny Audring (Leiden University) and Francesca Masini (University of Bologna), this is a unique handbook with a focus on morphology theories rather than morphological data. It covers a wide array of morphological theories, from traditional twentieth century models to current theoretical…

The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

My PhD research is devoted to studies of the conjectural cluster-algebraic symmetry in the theory of topological string, which is the simplest, however already non-trivial sector in the theory of string.

On Thursday 23 November, Professor Betty de Hart delivered the lecture ‘Exploring the Legal Archive on Race: Methodological Challenges’ as part of the lecture series ‘Reconsidering the Socio-Legal Gaze’ organized by the Van Vollenhoven Institute. Over 40 people attended the lecture, held online due…

The Centre for Legal Entrepreneurship and Innovation focuses on stimulating entrepreneurship and innovation in the legal sector. It builds a bridge between study and practice.

This political theory specialisation focuses on the concepts of legitimacy and justice—political philosophy’s core themes. Immersing yourself in theories, philosophical and theoretical methods, and complex cases, you will make the leap from opinion to analysis.

Imitation is, perhaps more than ever, constitutive of human originality.

The master in Cultural Analysis: Literature and Theory at Leiden University focuses on the study of literature from a comparative and theoretical perspective, with a special emphasis on literary movements and genres of the 19th, 20th, and 21st centuries. It covers a wide range of languages and cultures…
