1. van der Waals Density Functionals
Abstract : Methods using local or semi local approximations (LDA, GGA etc.) for the exchange-correlation energy in the density-functional theory (DFT) do not include van der Waals interactions. READ MORE

2. Estimating income inequality : large sample inference in finite populations
Abstract : During the last decades the interest in measuring income inequality has substantially increased. In this work we consider measures related to the Lorenz Curve, e g the Gini coefficient. These measures are decomposable^ g the inequality in disposable income can be assigned to various income sources. READ MORE

3. Symmetry in Randomness : Additive Functionals and Symmetries of Random Trees and Tree-Like Graphs
Abstract : Properties of symmetries in random trees and tree-like graphs are explored. The primary structures studied are Galton-Watson trees, unlabeled unordered trees as well as labeled subcritical graphs. READ MORE

5. Foundation of Density Functionals in the Presence of Magnetic Field
Abstract : This thesis contains four articles related to mathematical aspects of Density Functional Theory.In Paper A, the theoretical justification of density methods formulated with current densities is addressed. It is shown that the set of ground-states is determined by the ensemble-representable particle and paramagnetic current density. READ MORE
