Science

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

Van Saarloos Group (Soft Matter Theory)
The focus of our theoretical research is understanding the behaviour of soft condensed matter, physical matter which is deformed or structurally altered by thermal fluctuations or small stresses.

Dual Complexes of Semistable Varieties
This thesis is comprised of three chapters covering the theme of studying semistable varieties by looking at their dual combinatorial objects.

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

Theory
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…

Theorie van fermionpariteitomkeringen in supergeleiders
Majorana meets a mermaid

On the randommatrix theory of Majorana fermions in topological superconductors
The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

Algebra, Geometry and Number Theory (MSc)
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: theory and practice
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 Oxford Handbook of Morphological Theory
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…

Jan Zaanen Group (Quantum Matter Theory)
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.

Koenraad Schalm Group (String Theory and Experiment)
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…

Cultural Analysis: Literature and Theory (MA)
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…

Political Theory: Legitimacy and Justice (MSc)
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.

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

Memory: concepts and theory
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…

Theoryenriched practical knowledge in mathematics teacher education
This study looks at the question of how and at what level students in primary teacher education can integrate theory and practice, and how the organisation of their learning environment, focusing especially on mathematics and pedagogy, can contribute to that.

Femke Bakker, Hawks and Doves: Democratic Peace Theory Revisited
Is there a causal mechanism underlying the decision to attack another country when on the brink of war? If so, does this mechanism differ between regimetypes? Political scientist Femke Bakker (Leiden University) addresses this question from a political psychological and comparative perspective and…

The Roots of Intentionality in Aristotle´s Theory of Psychology
The relevance of intentionality to the interpretation of Aristotle was first suggested by Brentano in his Psychology from an Empirical Standpoint. Here we take our starting point from Brentano and investigate how Brentano’s concept of intentionality is rooted in Aristotle.
