1. Computing abelian varieties over finite fields
Sammanfattning : In this thesis we address the problem of developing effective algorithms to compute isomorphism classes of polarized abelian varieties over a finite field and of fractional ideals of an order in a finite product of number fields.There are well-known methods to efficiently compute the classes of invertible ideals of an order in a number field, but not much has previously been known about non-invertible ideals.

2. Quaternion Orders and Ternary Quadratic Forms Orders of Class Number One and Representations of Algebraic Integers by Quadratic Forms
Sammanfattning : Let R be the ring of integers in a totally real quadratic field K. The purpose of the thesis is to study totally definite quaternion R-orders and representations of elements in R by totally positive definite integral ternary quadratic forms. The thesis consists of three papers. LÄS MER
3. Bland hederligt folk. Organiserat sällskapsliv och borgerlig formering i Göteborg 1755 - 1820 : Honourable people. Organized social life and the making of the bourgeoisie in Gothenburg 1755-1820
Sammanfattning : This thesis deals with orders, clubs and societies and their impact on the making of the bourgeoisie in Gothenburg during the eighteenth and early nineteenth century. Clubs and societies worked as platforms for the articulation of the collective experiences among merchants, public officials, army officers, civil servants, and just as important their daughters and wives.

4. Med främmande bagage : Tankar och erfarenheter hos unga människor med ursprung i en annan kultur eller Det postmoderna främlingskapet
Sammanfattning : The present study is based on interviews with 22 youth and young adults. The perspective is phenomenological, since my aim has been to analyse and describe the everyday world as it presents itself to these young people. LÄS MER
5. Laser diode systems for photodynamic therapy and medical diagnostics
Sammanfattning : This work concerns techniques for improvement of the coherence properties of diode lasers so that they may be used in two specific medical applications: (Interstitial) photodynamic therapy (PDT) and laser-induced fluorescence diagnostics. In the first application, spatial coherence is crucial, since the treatment light should be delivered through relatively thin optical fibers to optimize treatment and to facilitate minimally invasive treatment.
