Combinatorial games are games for two competing players, moving in a turn-by-turn fashion, in which there is no chance nor hidden information⁠. Chess, checkers and the simpler tic tac toe are well-known examples of this class of games, as well as game of go⁠.

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

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

LIACS is a partner in RISE_SMA, an interdisciplinary, international network combining excellent scholars and practitioners to enable vigorous knowledge sharing and to develop solutions for contemporary challenges for Social Media Analytics (SMA).

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

Het Instituut Politieke Wetenschap blijft graag in contact met alumni. Van onze afstudeerders kunnen wij veel leren. En we helpen natuurlijk ook graag een handje om ‘onze’ politicologen in binnen- en buitenland met elkaar te verbinden.

The haplolepideous mosses (Dicranidae) comprise about 4000 species distributed over a wide range of habitats, with great gametophytic and sporophytic morphological variation. Their monophyly is well supported by the results of several molecular phylogenetic studies, which shed light on their relationships…

Alumni-activiteit

Hartje zomer en tóch de collegebanken in? Studenten uit de hele wereld komen naar Leiden en Den Haag voor een summer school. De onderwerpen variëren van taalkunde tot internationaal strafrecht en van natuurkunde tot biofarmacie. Docenten en studenten vertellen over leerzame en leuke momenten.

Hieronder vind je de antwoorden op een aantal veelgestelde vragen over toelating tot de klinische specialisaties van de Master Psychologie.

In april 2001 was Nederland het eerste land ter wereld dat het huwelijk openstelde voor paren van gelijk geslacht. Het afstammingsrecht maakt echter nog steeds onderscheid tussen gelijk en verschillend geslacht. Volgens Kees Waaldijk kan dat anders.

This book explores the spiritual potential of faith, mysticism and transcendence in answer to the dangers of a mythologised state and the sacro-sanctification of (liberal) democracy and its rule of law.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

This thesis considers multi-prover commitment schemes whose security is based on restrictions on the communication between the provers.

Cardiovascular disease is the number one cause of death worldwide. The most important risk factor for developing this disease is high cholesterol levels in the blood.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

The glycosylation reaction is a pivotal reaction in creating new and complex oligosaccharides.

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

Als een nieuwe methode is ontwikkeld om een (neuro-)psychologische aandoening of hieraan gerelateerde gedragsfactoren te herkennen en te behandelen, kan deze nog niet direct in de klinische praktijk worden ingezet. Eerst moet de methode geëvalueerd worden, bij voorkeur in gerandomiseerde, gecontroleerde…

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.
