1. The fundamental theorem of calculus : a case study into the didactic transposition of proof
Abstract : The relationship between academic mathematics as practiced by researchers at universities and classroom mathematics (the mathematical practices in classrooms in primary, lower and upper secondary education as well as in undergraduate university education) is a fundamental question in mathematics education. The focus of the study presented here is on how this relationship is seen from the perspective of mathematics education and by researching mathematicians, with a focus on proof. READ MORE

2. Positive vector bundles in complex and convex geometry
Abstract : This thesis concerns various aspects of the geometry of holomorphic vector bundles and their analytical theory which all, vaguely speaking, are related to the notion of positive curvature in general, and L^2-methods for the dbar-equation in particular. The thesis contains four papers. READ MORE

3. Theory and Applications of Tri-Axial Electromagnetic Field Measurements
Abstract : Polarisation, which was first studied in optics, is a fundamental property of all electromagnetic fields. A convenient way to describe the polarisation of two dimensional electromagnetic fields is given by the Stokes parameters. This thesis deals with different aspects of wave polarisation and electromagnetic field measurements. READ MORE

4. Miniaturized Hard Waveguides in Multifunction Array Antennas
Abstract : Recent advances in technologies of wireless communications systems have led to an increasing desire for several antennas performing diverse functions at different frequencies to be integrated into a common radiating aperture. This gives rise to the so-called multifunction antenna, which affords the saving of scarce premium real estate and can alleviate problems arising from excessive antenna protrusions in aspects such as aerodynamics, aesthetics, and stealth capability in military applications.

5. Essays on Strategy-proof Social Choice
Abstract : This thesis makes a contribution to strategy-proof social choice theory, in which one investigates the conditions under which it is possible to construct social choice functions (i.e. READ MORE
