  1. 1. Generalized Abelian Gauge Theory & Generalized Global Symmetry

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Emil Hössjer; [2020]
    Nyckelord :Differential characters; Wilson lines; generalized global symmetry; BF theory; Maxwell theory; spontaneous symmetry breaking; intersection number; selection rules; Noether theorem; sphere bundle; t Hooft operator;

    Sammanfattning : We study Cheeger-Simons differential characters in order to define higher form U(1) gauge fields and their Wilson lines. We then go on to define generalized global symmetries. This is a topological formulation of symmetries which has interesting consequences when the charged operators extend through space. LÄS MER

  2. 2. Ethnic Discrimination in London’s Housing Market – Are Bangladeshi women worse off applying for housing compared to White women?

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Matilda Fredholm; Sonja Stanicic; [2019-02-15]
    Nyckelord :Taste-based discrimination; Statistical discrimination; London housing market; Bangladeshi; Correspondence testing design; Ethnic discrimination;

    Sammanfattning : This study investigates ethnic discrimination for sublets in London’s rental housing market. By applying an experimental design, four female fictitious characters were created to apply for housing advertisements on the website Gumtree. LÄS MER

  3. 3. Tritrophic interaction between whiteflies, insect pathogenic fungi and host plant : biology of whitefly, Bemisia afer

    L3-uppsats, SLU/Dept. of Ecology

    Författare :Ethel Cavén; [2007]
    Nyckelord :Aleyrodidae; Bemisia afer; tritrophic interactions; Paecilomyces fumosoroseus; Lecanicillium sp.; sweetpotato; tomato; Peruvian pepper; bean; lifecycle; entomopathogens;

    Sammanfattning : The study was preformed at the International Potato Centre, CIP, in the capital of Peru, Lima on the west coast of South America and the Ecology Department, SLU, Uppsala, Sweden. The main purpose of this thesis was to evaluate the tritrophic interaction and efficacy of entomopathogens on the whitefly on different host plants and different species of fungus. LÄS MER
