2. 1. Algorithmic Methods in Combinatorial Algebra

   Author : Anna Torstensson; Algebra; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; algebraic geometry; field theory; Number Theory; maximal symmetry group; resultant; SAGBI basis; Orthogonal decomposition; algebra; group theory; Talteori; fältteori; algebraisk geometri; gruppteori;

   Abstract : This thesis consists of a collection of articles all using and/or developing algorithmic methods for the investigation of different algebraic structures. Part A concerns orthogonal decompositions of simple Lie algebras. The main result of this part is that the symplectic Lie algebra C3 has no orthogonal decomposition of so called monomial type.

4. 2. Some Resolvent Estimates in Harmonic Analysis

   Author : Anders Dahlner; Matematik (naturvetenskapliga fakulteten); []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; field theory; Number Theory; algebra; algebraic geometry; Talteori; group theory; Tauberian theorem. Quantitative inversion. Cesaro operator. Bishops property beta.; algebraisk geometri; fältteori; gruppteori;

   Abstract : This thesis contains three papers about three different estimates of resolvents in harmonic analysis. These papers are: Paper 1. ``A Wiener tauberian theorem for weighted convolution algebras of zonal functions on the automorphism group of the unit disc'' Paper 2. ``Uniform spectral radius and compact Gelfand transform'' Paper 3.

5. 3. Kantor Triple Systems

   Author : Daniel Mondoc; Matematik (naturvetenskapliga fakulteten); []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gruppteori; fältteori; algebra; algebraic geometry; group theory; Talteori; field theory; Number Theory; Composition algebras; Jordan algebras; Kantor triple systems; Lie algebras; Jordan triple systems; algebraisk geometri;

   Abstract : The main purpose of this thesis is to study real exceptional Kantor triple systems. In the first paper we first prove the known results in both the real and complex classical cases of K-simple Kantor triple systems. In the real classical case our approach gives somewhat simpler formulas. READ MORE

6. 4. Modelling Allelic and DNA Copy Number Variations using Continuous-index Hidden Markov Models

   Author : Susann Stjernqvist; Matematisk statistik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hidden Markov models; DNA copy number; allelic copy number; Markov chain Monte Carlo;

   Abstract : In human cells there are usually two copies of each chromosome, but in cancer cells abnormalities could exist. The differences consist of segments of chromosomes with an altered number of copies. There can be deletions as well as amplifications and the lengths of the segments can also vary. READ MORE

7. 5. Management Control in Services. A Contingency Study of Responsibility Accounting in Highly Interactive Services

   Author : Sven Modell; Företagsekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; organizational technology; responsibility accounting; services; management control; contingency theory; agency theory; Management of enterprises; Företagsledning; management;

   Abstract : This report examines the use of management control in services, with particular reference to the role of formal control systems in attributing and devolving responsibility within organizations. The study draws extensively on the service as well as the management control literature and advances an analytical framework based on a process-oriented approach to responsibility accounting.
