1. Building Data for Stacky Covers and the Étale Cohomology Ring of an Arithmetic Curve : Du som saknar dator/datorvana kan kontakta [email protected] för information
Abstract : This thesis consists of two papers with somewhat different flavours. In Paper I we compute the étale cohomology ring H^*(X,Z/nZ) for X the ring of integers of a number field K. As an application, we give a non-vanishing formula for an invariant defined by Minhyong Kim. READ MORE

2. Stacky Modifications and Operations in the Étale Cohomology of Number Fields
Abstract : This thesis consists of 4 papers. In Paper A we define stacky building data for stacky covers in the spirit of Pardini and give an equivalence of (2,1)- categories between the category of stacky covers and the category of stacky building data. READ MORE

3. On Methods for Solving Symmetric Systems of Linear Equations Arising in Optimization
Abstract : In this thesis we present research on mathematical properties of methods for solv- ing symmetric systems of linear equations that arise in various optimization problem formulations and in methods for solving such problems.In the first and third paper (Paper A and Paper C), we consider the connection be- tween the method of conjugate gradients and quasi-Newton methods on strictly convex quadratic optimization problems or equivalently on a symmetric system of linear equa- tions with a positive definite matrix.

4. Towards Correct and Efficient Program Execution in Decentralized Networks: Programming Languages, Semantics, and Resource Management
Abstract : The Internet as of 2014 connects billions of devices, and is expected to connect tens of billions by 2020. To meet escalating requirements, networks must be scalable, easy to manage, and be able to efficiently execute programs and disseminate data. The prevailing use of centralized systems and control in, e.g. READ MORE

5. Resistivity and Surface Wave Seismic Surveys in Geotechnical Site Investigations
Abstract : The adaptation of geophysical methods for civil engineering purposes represents an important contribution to the development of geotechnical site investigation methodology. The term geotechnical site investigation here refers to all investigations performed prior to or during construction; i.e. READ MORE
