2. Multiconfigurational perturbation theory
Abstract : The aim of the thesis is to analyze a method which describes the electron correlation in atoms and molecules. The method is based on Rayleigh-Schrödinger perturbation theory with a partitioning of the Hamiltonian into a fairly simple zeroth-order operator and a perturbation operator. READ MORE

3. Topics in perturbation theory : From IBP identities to integrands
Abstract : In this thesis we present different topics in perturbation theory. We start by introducing the method of integration by parts identities, which reduces a generic Feynman integral to a linear combination of a finite basis of master integrals. READ MORE

4. The Powers of Perturbation Theory : Loops and Gauge Invariance in Particle Physics
Abstract : The Standard Model is the best particle physics theory we have, but there are still phenomena that it cannot explain. In this thesis I have worked on two different projects that connect to two of the biggest unsolved questions of the Standard Model. READ MORE

5. The flight perturbation problem : operational aircraft rescheduling
Abstract : When there is a perturbation in a carefully planned flight schedule, e.g. an aircraft breakdown, it is important to minimize the negative consequences of this disturbance. In this thesis, a model and a number of solution strategies for the Flight Perturbation Problem is presented. READ MORE
