PhD thesis

Thesis I was main supervisor for since 1999. The links are to the last version I have access to. The thesis are usually not final versions; further corrections and editing have been done before printing, and there are errata lists associated to the thesis. There may be separate files for figures, tables and references; if so they are not included in this directory. Important to remember is that Swedish thesis are composed of a "summary" and a number of chapters circling around a common theme. The chapters are independent articles which have been independently published (for a few cases the articles are only a chapter in the thesis and never become published in another way). Those chapters are not included in the offered files. Thus, if you want to study the material in depth, you are advised to look into a printed copy! For the theses since 2002, the link is not to my web and there are probably no errata.
