If X is a locally compact Hausdorff space, then a representation of the complex C* algebra C_0(X) on a Hilbert space $H$ is given by a spectral measure that takes its values in the orthogonal projections on $H$.

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

Our Advanced Master Air and Space Law (LL.M.) combines public air law, private air law and space law from a European and an international perspective.

Here you will find an overview of the Spaces for Active Teaching and Learning already implemented at Leiden University and LUMC. These rooms vary in size, location, material affordances, and technological affordances, and thus vary in the forms of pedagogy they best support. You can use this site as…

The International Institute of Air and Space Law is one of the leading international academic research and teaching institutes in the world, specialising in legal and policy issues regarding aviation and space activities in the broadest sense of the word.

How are night spaces imagined, produced, experienced and narrated by migrant communities in Europe? This research project considers this question in eight European cities: Aarhus, Amsterdam, Berlin, Cork, Galway, Lisbon, London, Rotterdam. Authorities have historically wrestled with the issue of night-time…

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

Large telescopes can look so deep into the Universe that they can also look back billions of years in time. From 2018, the successor of the Hubble Space Telescope, the James Webb Space Telescope, will be able to see the period just after the Big Bang, when the first stars and galaxies formed. Astronomers…

Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

Physical Violence refers to violence related to criminal activities, violence perpetrated in interpersonal conflict such as in the domestic sphere, and socio-political violence. It ranges from mass shootings such as Columbine and Virginia Tech, to nighttime violence, alcohol-related violence, violent…

In this thesis we study the moduli space of genus g curves, and the differential forms that occur naturally on this moduli space.

The development of space resource activities is happening now. In the absence of a clear framework to govern these activities, there is a need to examine the concepts that are being discussed in order to ensure that they meet existing treaty obligations regarding on-orbit operations and space resource…

The International Institute of Air and Space Law (IIASL) offers PhD candidates the possibility to enroll in the IIASL PhD Track. It is designed for 'external' PhD candidates (buitenpromovendi), who seek to pursue a PhD in Air Law or Space Law while honouring their professional commitments in paralle…

This volume investigates how urban growth and prosperity transformed the cities of the Roman Mediterranean in the last centuries BCE and the first centuries CE, integrating debates about Roman urban space with discourse on Roman urban history.

The Netherlands Ministry of Defense and Ministry of Security and Justice have requested the Centre for Terrorism and Counterterrorism to complete a research project on cyber governance from a policy perspective.
