The aims of the project are to: further clarify 'inhibition by safety'; explore and describe all possible sagety factors, with a special focus on the primary human safety source: social connectedness; reviewing prolonged stress responses without stressors.

This paper describes the development process of voting behavior in Chile; particularly the relationship between the class voting theory and the theory of cultural post-materialist vote is investigated. This research deals with Chile as a case study, a developing country with a relatively stable democracy…

In this thesis three different topics in number theory are studied.

Data theory research on the analysis on the multidimensional data

The key purpose of this project is to study tautological relations on the level of closed differential forms or even integral cochains (i.e. we don't take classes in cohomology).

The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

Most of current public-key cryptography is considered insecure against attacks from sufficiently powerful quantum computers. Post-quantum cryptography studies methods to secure information resistant against such attacks. One proposal is isogeny-based cryptography, which bases its security on computational…

Stochastic resetting is simple enough to be approached analytically, yet modifies stochastic processes in a non-trivial way.

In this thesis, rational points on K3 surfaces are studied. In the first part of Chapter 1 the Brauer group and the the Brauer-Manin obstruction are introduced.

The subject of this thesis, ‘Approach to Markov Operators on Spaces of Measures by Means of Equicontinuity’, combines an analytical and probabilistic approach to Markov operators.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

Continuous optimization is never easy: the exact solution is always a luxury demand and the theory of it is not always analytical and elegant.

Deze master specialisatie behandelt een breed scala aan wetenschappelijke onderwerpen, waaronder High Energy Physics and Particle Cosmology, Theoretical Physics of Life Processes en Condensed Matter Theory.

Om intelligentere en liefst ook sociale robots en computersystemen te bouwen, moet er eerst meer kennis komen over de manier waarop mensen informatie interpreteren. Max van Duijn en Tessa Verhoef doen onderzoek op het snijvlak tussen sociale wetenschap en AI.

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 this dissertation, matching, entropy, holes and expansions come together. The first chapter is an introduction to ergodic theory and dynamical systems.

In this thesis, we present new laboratory data of interstellar dust analogues.

De minor Creative Strategies for a Society in Change (CSSC) legt een verbinding tussen het verkrijgen van inzicht in creatieve maakprocessen en het verkennen van maatschappelijke problematieken die kenmerkend zijn voor onze tijd.

Op 1 april 2020 verdedigde Marc Broekema zijn proefschrift 'Cognitive Bias in the Judgment of Business Valuations and Valuators'. Het promotieonderzoek is begeleid door promotor prof. dr. J.I. van der Rest.

In this thesis, we study travelling waves in stochastic reaction-diffusion equations. We extend techniques from the deterministic theory for travelling waves to apply to the stochastic version, which allows us to compute the stochastic wave speed and shape, and draw conclusions on the stability of the…

Deze tweejarige opleiding heeft twee componenten. De eerste is een meer analysegerichte component, met onderwerpen als dynamische systemen, differentiaalvergelijkingen, kansrekening en stochastiek, percolatie of wiskunde in de life sciences. De andere betreft een meer algebra- of meetkundegerichte component,…

Assuming everywhere good reduction we generalize the class number formula of Taelman to Drinfeld modules over arbitrary coefficient rings.
