The research project ‘Adaptive Semi-Strong Ecosystem Dynamics’ of Prof.Dr. Arjen Doelman is selected for funding as one of the 7 research projects within the program Mathematics of Planet Earth (MPE) of NWO.

In this thesis we construct an extension associated with the Furstenberg compactification of symmetric space of noncompact type. From this extension we get a cycle in equivariant KK-theory representing the extension. The construction of the extension and the corresponding cycle is a generalization of…

Publication (in Dutch) about mentoring in higher education.

The coronacrisis is emerging as the ultimate test for political leaders. How do national political leaders get ahead or behind ‘the curve’ of fast-changing dynamics. Martin Lodge (London School of Economics and Political Science) and Arjen Boin (Leiden University Institute of Political Science) look…

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…

Research project 'QUAD'

Never has good policy been so important. From unemployment and a lack of affordable housing to regulating cryptocurrencies and protecting against cybersecurity threats, the challenges we face are complex and global. The text explains how policymaking works: from the emergence of policy ideas to deciding…

This project investigates the capacities of EU institutions to coordinate the responses of member states to critical events.

What explains the difference between successful and less successful crisis responses, and how can these lessons be translated into adaptation strategies that societies can use to navigate through future crises?

In dit onderzoek worden orde isomorfismen en orde antimorfisme bestudeerd in het algemene kader van partieel geordende vector ruimten.

This thesis describes how complex and real-world relevant analytical solutions can be found starting from a simple Nagumo problem posed on one or two-dimensional lattices.

This thesis consists of three papers that are centered around the common theme of Hausdorff uo-Lebesgue topologies and convergence structures on vector lattices and on vector lattices and vector lattice algebras of order bounded operators.

De Nederlandse geschiedenis is nauw verbonden met die van de wereld als geheel. Door migratie, handel en kennisuitwisseling beïnvloedden mensen elkaar over grotere afstanden en intensiever dan we lang dachten. Wereldgeschiedenis van Nederland toonde in meer dan honderd verhalen hoe internationaal de…

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.

The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

This thesis mainly extends the theory of positive operators on Riesz spaces to a setting of pre-Riesz spaces.

We consider the propagation of electrical signals through nerve fibres.

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

In this thesis we study bistable reaction-diffusion equations on lattice domains.

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

The symposium is open to all registered participants and consists of a one-day programme and a poster session.

A tidal basin is an inland sea which is almost entirely enclosed by land and connected to the open sea by a tidal inlet. Through the tidal inlets interaction takes place between the tidal basin and the open sea.

The Kroese-Duijsters Symposia aim to provide researchers from different fields and different career stages to meet in an informal setting, to stimulate discussions and to start new collaborations. The Kroese-Duijsters Symposia started in 2022 and we are pleased to invite you to the 4th Kroese-Duijsters…

Security and Legitimacy is one of the three organisational clusters of the Institute of Political Science.

In what way can teachers support and enlarge student engagement in a blended learning context?

Effective innovation methodologies which lead to sustainable educational transformation require room for the development of teacher agency and at same time solve systemic problems. The Change Laboratory methodology combines both.

ICLON conducts research into further and higher education.

The Mathematical Institute has a rather liberal management structure. Tasks and responsibilities are distributed among the staff. Important decisions are taken by consensus. Various organisational divisions are featured below.

Learning analytics tracks students’ online learning activities in order to support their learning. But what if most of their learning takes place offline, out of sight of digital eyes?

How do university lecturers perceive and exercise teacher agency, and what approaches can effectively explore agentic actions and underlying beliefs?
