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.

In romantic love, we often invoke an idiom of infinity—for instance, when we promise to love each other forever, or declare the other to be the one. But what does this metaphysical appeal signify? And how can such a promise of infinite love be made within the bounds of a finite life? In attempt to answer…

In love, we like to use great words. We promise to love each other ‘forever’ and praise the beloved as nothing less than ‘the one’ . Meanwhile, we know very well that we don’t live eternally and that we may find our ‘true love’ one day on the opposite side of the divorce table. So why do we continue…

This thesis is is made of three parts. The first part describes a generalization of the Chabauty's method, that can be used to determine the rational points of a curve such that s+g>r+1, where g is the genusof the curve, r is the rank of the Mordell-Weil group of the jacobian of the curve and s is…

Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…

This thesis studies the geometry of representation varieties and character stacks. These are spaces parametrizing the representations of a finitely generated group, typically the fundamental group of a compact manifold, into an algebraic group G.

Let A be a commutative algebraic group over a field K, and let G be a finitely generated subgroup of the K-rational points of A. The purpose of this thesis is to study the degrees of the Kummer extensions relative to A,K and G.

An algorithm is discussed to compute the exponential representation of principal units in a finite extension field F of the p-adic rationals.

In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations.

Is criminal disenfranchisement compatible with a democratic political order? This article considers this question in light of a recently developed view that criminal disenfranchisement is justified because it expresses our commitment to democratic values.

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

This dissertation provides a comprehensive overview of the grammar of Bantawa, a Kiranti (Rai) language spoken in Eastern Nepal.

The infinite is endlessly fascinating. As finite beings, we will never be able to fully grasp the infinite. Yet the topic keeps resurfacing in philosophy – apparently, we cannot escape it either. Philosopher Victor Gijsbers guides the reader through the most important questions about the infinite in…

On a structural level, the properties featured by a majority of mechanical metamaterials can be ascribed to the finite number of soft internal degrees-of freedom allowing for low-energy deformations.

This dissertation presents a grammar of Khwarshi, a Nakh-Daghestanian language.

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

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.

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

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

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

This dissertation consists of two parts, each of which considers a different research area related to random interval maps. In the first part we are interested in random interval maps that are critically intermittent.
