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.

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

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

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

In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

The basic program comprises a total of thirteen courses organized by the Research School, that have been purpose-developed for training and support of PhD students and Research MA students who specialize in Medieval Studies (history, art history, and literary history, in particular). The courses have…

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 multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

Integrating life cycle assessment (LCA) with life cycle costing (LCC) offers the opportunity to simultaneously analyze the environmental and economic aspects of product alternatives, for the integration of which a unified computational has been proposed by Heijungs et al. (2013) [1]. The project aims…

This thesis discusses the discovery potential of Intensity Frontier experiments.

Evolution acts via mutations in amino acid sequences. Substitution of essential amino acids leads to a nonfunctional protein. l.

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

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.

In Europe a number of production and communication strategies have long tried to establish local products as resources for local development. At the foot of the Alps, this scenario appears in all its contradictions, especially in relation to cheese production. The Heritage Arena focuses on the saga…

Current therapies for patients with atherosclerosis are targeted primarily on reducing blood cholesterol, but this fails to prevent a large number of cardiovascular events.95 In order to identify new therapeutic strategies for treating atherosclerosis, it is important to study the interactions between…

In this Thesis, novel charge induction mechanisms of ionic liquids are treated, tested and experimented on complex oxides, in particular cuprates.
