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

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

The Institute of Environmental Sciences has carried out and participates in several projects that deal with the analysis of energy systems.

Het onderzoek van dit programma is gecentreerd rond dynamische systemen, functionele analyse en hun interactie.

How the global distribution of vegetation stands dominated by arbuscular and ectomycorrhizal plants relate to principle aspects of belowground carbon accumulation processes?

Het Joint Legal Technologies Program is een multidisciplinaire opleiding die een brug slaat tussen de juridische en technische wereld. Deze opleiding wordt aangeboden in samenwerking met de Open Universiteit.

Empirical Legal Studies in Leiden focust op het bouwen van een interdisciplinaire gemeenschap van rechtsgeleerden en sociale wetenschappers die samen juridische vraagstukken onderzoeken op het snijpunt van recht en gedrag, waarbij diverse soorten methoden worden gebruikt.

Overlevingsanalyse is een onderzoeksgebied dat zich richt op het bestuderen van de tijd tot het optreden van een specifieke uitkomst.

D1.2 reports on the findings of an analysis of framework conditions relevant in the context of the data economy from a legal, a socio-economic and a technological perspective. The analysis is a key foundation for the creation of an initial, heuristic model of the European data economy. The deliverable…

Arithmetic geometry concerns the number-theoretic properties of geometric objects defined by polynomials. Mathematicians are interested in the rational solutions to these geometric objects.
