Stochastic resetting is simple enough to be approached analytically, yet modifies stochastic processes in a non-trivial way.

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

Continuous optimization is never easy: the exact solution is always a luxury demand and the theory of it is not always analytical and elegant.

In this thesis, we study travelling waves in stochastic reaction-diffusion equations. We extend techniques from the deterministic theory for travelling waves to apply to the stochastic version, which allows us to compute the stochastic wave speed and shape, and draw conclusions on the stability of the…

As of 1 June, Floske Spieksma has been appointed Professor at the Mathematical Institute in Leiden. Her field of study is Stochastic Decision-Making. Within this field, researchers develop mathematical techniques to analyse and improve processes within organisations. ‘As a professor, I hope to safeguard…

The correctness of computational systems is of great importance to our society, since it becomes ever more reliant on the benefits of computing.

Industrial manufacturing processes, such as the production of steel or the stamping of car body parts, are complex semi-batch processes with many process steps, machine parameters and quality indicators.

Gibbs measures, as used in Statistical Mechanics, have a definition that is remarkably similar to the definition ofg-measures, used in dynamical systems.

The subject of this thesis, ‘Approach to Markov Operators on Spaces of Measures by Means of Equicontinuity’, combines an analytical and probabilistic approach to Markov operators.

On the 4th of June, Saskia Lensink successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Saskia Lensink on this achievement!

Making choices is part of life. You make larger or smaller choices in everything you do, and you progress from one choice/decision to the next. All decision-making processes involve three aspects: making a choice, experiencing that choice and reflecting on it.

This project examines how speakers store and process regular pitch variation.

Real-life processes are characterized by dynamics involving time. Examples are walking, sleeping, disease progress in medical treatment, and events in a workflow.

Smartphone behaviors are so common but how does the brain generate this behavior? The Cognition in the digital environment laboratory (CODELAB) investigated the brain activity surrounding smartphone interactions with the help of Artificial Intelligence. According to their research, the brain fluidly…

This project looks at how the native language influences processing mechanisms of non-native language(s) as well has how it influences brain structure and functional connectivity.

Legitimacy is generally a term that is associated with the state. The term surfaces when there are problems with state legitimacy—when it is lacking or absent. This present volume attempts to think through the relevance of the concept of legitimacy for other political actors than the state.

This project is aimed at 1) elucidating the role of attention in itch and pain, including orientation, and attentional disengagement (i.e., directing attention away) from itch and pain; and 2) modifiability of these attentional processes.

Basketry, cordage and textiles made of plant fibers or bark are rarely preserved in the archaeological record. By means of experimental archaeology and microwear analysis, we obtain indirect evidence about this important craft.

To what extent and how do identity processes influence health behavior?

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

People who have taken antibiotics in the past three months pay more attention to negative facial expressions, according to research by postdoc Katerina Johnson and assistant professor Laura Steenbergen. This may explain how antibiotics increase the risk of developing depression.

How does task context affect children’s word productions?

This book provides a comparative analysis of the process of breach across ten different European jurisdictions by identifying and elaborating a number of key analytical themes through which the different systems can be compared and evaluated.

The group Theoretical Physics of Life Processes, led by Helmut Schiessel, focuses on the physics of chromatin, the DNA-protein complex that fills the nuclei of eukaryotic cells.

In this project, we plan to combine two strands of research in speech processing: (a) the impact of prosody on speech processing and (b) the impact of musical training on speech processing. In our project we will test 8 year-old children with different degrees of musical training: (a) primary school…

What holds people together and what makes them willing to fit within larger political structures? Our project examines this question in the practices of dynastic rulership in Eurasia ca. 1300-1800.
