This thesis has three main parts. The first part gives an algorithm to compute Hilbert modular polynomials for ordinary abelian varieties with maximal real multiplication. Hilbert modular polynomials of a given level b give a way of finding all of the abelian varieties that are b-isogeneous to any given…

In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

In the first part, we introduce a new condition, called toric-additivity, on a family of abelian varieties degenerating to a semi-abelian scheme over a normal crossing divisor.

Dit op casestudies gebaseerde Engelstalige boek over multivariate analyse voor gevorderde studenten in de geesteswetenschappen legt de nadruk op beschrijvende, exploratieve analyses van verschillende soorten datasets uit een breed scala van subdisciplines, waarbij het gebruik van multivariate analyse…

This PhD thesis concerns the topic of arithmetic geometry. We address three different questions and each of the questions in some way is about counting how big some set is or can be.

Breeding for resistance becomes more and more important because we want to reduce the use of pesticides. A fast and cheap alternative can be to make use of morphological or chemical markers.

Op 3 september 2019 verdedigde Ilektra Antonaki haar proefschrift 'Privatisations and golden shares: Bridging the gap between the State and the market in the area of free movement of capital in the EU'. Het promotieonderzoek is begeleid door promotor prof.dr. S.C.G. Van den Bogaert.

De overlegeconomie is nog springlevend, concludeert Jeroen Touwen in een lijvige studie van 385 pp. naar de geschiedenis van zestig jaar overleg en onderhandelen in de Nederlandse economie. Dankzij formele regelgeving, bereidheid tot aanpassen, het afbakenen van marktwerking binnen nauwgedefinieerde…
