In this work we review various findings in the planar quantum physics with the special emphasis on the two-component quantum electrodynamics in three-dimensional spacetime (QED3) with the Chern-Simons (CS) term. First the classical electrodynamics is briefly outlined. Then we construct and classify the unitary irreducible representations of the Poincaré group and connect them to various covaria...

Cyclists often have multiple criteria in mind when planning a route. They do not only consider the length of the route, but also the (perceived) safety or the environment of the route. Cycleways through park are often more attractive than heavily used roads. But not every cyclist weights these criteria the same way and even for one cyclist the weighting may depend on his current situation. In a...

This thesis examines the computational complexity of transmission network expansion planning which is defined as follows. Given a transmission grid of generators and consumers (nodes) connected by transmission lines (edges) with certain flow capacities, where should new lines be added at minimum cost such that all given capacity constraints are fulfilled? In its original mixed-integer non-linea...
