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…

The research of the Algebra, Geometry and Number Theory programme ranges from fundamental mathematical theory to algorithms and applications.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

This book addresses the definition of history and how people are influenced by it.

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

Master classes offer students a deep dive into a topic that lies close to an alum’s heart. These range from explorations of complicated historical and political issues, to practical advice on careers.

The Honours Academy provides 35 to 40 Bachelor Honours Classes each year. These are for small group and use innovative modes of instruction. As Honours Classes are open to students from all faculties, the students exchange knowledge and are challenged to leave the beaten track.

At Leiden University, students with enquiring minds have the opportunity to take on an extra academic challenge alongside their regular studies. Graduate students can choose between various interdisciplinary Master Honours Classes.

Leiden University gives inquisitive students the opportunity to follow an extra programme or classes alongside their regular bachelor’s programme. These are called Honours College and Honours Classes.

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.

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.

If you are working or studying in Egypt, but find it hard to communicate in spoken Egyptian Arabic, then this course is perfect for you. In ten weeks’ time, you will be equipped with the communicative skills in Egyptian Colloquial Arabic needed to engage in basic social interactions. Scheduled in the…

If you are in doubt about going to the Conservatory or the University, the PRE Class Practicum Musicae might be something for you!

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.

Developing a method to simplify polynomials in complex curves

Majorana meets a mermaid

Promotor: S.J. Edixhoven

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…

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 course Popular Music: Selling Rebellion offers a unique opportunity to explore the popular music world from the point of view of its relation to both politics and the industry.

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…

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…

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.

'Politics of Withdrawal' considers the significance of practices and theories of withdrawal for radical thinking today.

The Summer School on International Humanitarian Law is designed by the Grotius Centre Kalshoven-Gieskes Forum on International Humanitarian Law. The 6th edition will take place from 4 to 8 July 2022 in The Hague.

An international and interdisciplinary collaborative effort, the Honours Class ‘Sustainability Beyond Frustration: Saving the Planet as an Academic Skill’ aims to present students’ ideas to sustainability experts that know how to bring them to fruition.

The terms ‘social’ , ‘collective’ or ‘public’ memory, are often contrasted with ‘private’, ‘individual’ or ‘personal’ memory. All these terms derive from a fairly new and interdisciplinary scholarly field that is often referred to as ‘memory studies’, and that according to some critics has developed…
