1. Combinatorics and topology related to involutions in Coxeter groups
Sammanfattning : This dissertation consists of three papers in combinatorial Coxeter group theory.A Coxeter group is a group W generated by a set S, where all relations can be derived from the relations s2 = e for all s ? S, and (ss′)m(s,s′) = e for some pairs of generators s ≠ s′ in S, where e ? W is the identity element and m(s, s′) is an integer satisfying that m(s, s′) = m(s′, s) ≥ 2. LÄS MER
2. Generalised Ramsey numbers and Bruhat order on involutions
Sammanfattning : This thesis consists of two papers within two different areas of combinatorics.Ramsey theory is a classic topic in graph theory, and Paper A deals with two of its most fundamental problems: to compute Ramsey numbers and to characterise critical graphs. More precisely, we study generalised Ramsey numbers for two sets Γ1 and Γ2 of cycles. LÄS MER
3. Kollektivavtalsrätten : en rättsvetenskaplig berättelse
Sammanfattning : The collective agreement is considered to be the single most important method of regulating the labour market in Sweden. Its importance is emphasised by the fact that there is no legislation concerning wages, and that labour-market legislation often can be derogated from by collective agreements (quasi-mandatory statutes).

5. Structural Determination of Drug Metabolites from Doping Classed Compounds Using Mass Spectrometry
Sammanfattning : Doping control in equine sports is important for a fair competition, but also to ensure the integrity of the betting system, as well as for animal welfare reasons. To detect the use of illicit compounds, screening for the parent compound is common. However, by using a metabolite as the analytical target instead, the detection time can be prolonged. LÄS MER
