Isogeny graphs, modular polynomials, and applications
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…

Wireless Random-Access Networks and Spectra of Random Graph
This thesis is divided into two parts. In Part I we study metastability properties of queue-based random-access protocols for wireless networks. The network is modeledas a bipartite graph whose edges represent interference constraints. In Part II we study spectra of inhomogeneous Erdős-Rényi random…

Complex Patterns in Streams
The goal of the project is the development of stream mining techniques for complex patterns such as graphs. We will try to extend the existing state-of-the-art techniques into two, orthogonal directions: on the one hand, the mining of more complex patterns in streams, such as sequential patterns and…

On metrics and models for multiplex networks
In this thesis, we extend the concept of null models as canonical ensembles of multi-graphs with given constraints and present new metrics able to characterize real-world layered systems based on their correlation patterns.

Travelling patterns on Discrete Media
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.

A monodromy criterion for existence of Neron models and a result on semi-factoriality
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.

Breaking of ensemble equivalence for complex networks
For many system in statistical physics the microcanonical and canonical ensemble are equivalent in the thermodynamic limit, but not for all.

Intense automorphisms of finite groups
In this thesis we classify the pairs (p,G), where p is a prime number and G is a finite p-group possessing an intense automorphism, i.e. an automorphism that sends each subgroup of G to a G-conjugate, that is non-trivial and whose order is coprime to p.

Promovendus Robbert van Eijk maakt privacycomponent meetbaar bij online advertenties
Je kijkt op Facebook om te zien of iemand uit je vrienden- of familiekring nog iets interessants heeft meegemaakt. Je oog valt op een reclame van een vakantie-aanbieder. Toevallig, denk je, want voordat je op Facebook kwam heb je elders op internet gezocht naar een vakantiebestemming. Maar dat is niet…

Algemeen kader voor systeemanalyse in Natuurkunde en Economie
Wetenschappers moeten vaak complexe systemen analyseren zonder de belangrijke parameters te kennen of zelfs zonder toegang tot alle informatie. Een groep netwerktheoretici, waaronder Diego Garlaschelli (IMT Lucca/Leiden), heeft nu een review artikel gepubliceerd in de eerste editie van Nature Reviews…
