1. Discussions on Dai-Freed Anomalies
University essay from Uppsala universitet/Teoretisk fysikAbstract : In both field theories of high energy physics and field theories of condensed matter theories anomalies have been imposing constraints and bringing up new theories. While the perturbational and local anomalies from triangle diagrams are well-developed, we follow and review two works leading to non-perturbational global anomalies both related with Atiyah-Patogi-Sieger (APS) index theorem.

2. Supersymmetric Quantum Mechanics, Index Theorems and Equivariant Cohomology
University essay from Uppsala universitet/Teoretisk fysikAbstract : In this thesis, we investigate supersymmetric quantum mechanics (SUSYQM) and its relation to index theorems and equivariant cohomology. We define some basic constructions on super vector spaces in order to set the language for the rest of the thesis. READ MORE

3. Structural Diagnosis Implementation of Dymola Models using Matlab Fault Diagnosis Toolbox
University essay from Linköpings universitet/FordonssystemAbstract : Models are of great interest in many fields of engineering as they enable prediction of a systems behaviour, given an initial mode of the system. However, in the field of model-based diagnosis the models are used in a reverse manner, as they are combined with the observations of the systems behaviour in order to estimate the system mode.

4. On Eggs and Baskets: An Empirical Study of the Relation between Debt Capacity and Corporate Diversification
University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomiAbstract : Economic Theory suggests that corporate diversification has a positive impact on firm debt carrying capacity. The cash flows of a diversified firm's segments result, when imperfectly correlated, in reduced volatility of total cash flows and increased debt carrying capacity. READ MORE

5. Index Theorems and Supersymmetry
University essay from Uppsala universitet/Teoretisk fysikAbstract : The Atiyah-Singer index theorem, the Euler number, and the Hirzebruch signature are derived via the supersymmetric path integral. Concisely, the supersymmetric path integral is a combination of a bosonic and a femionic path integral. READ MORE
