  1. 16. Higgs inflation

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Erik Schildt; [2018]
    Nyckelord :inflation; Higgs inflation; nonminimal coupling; conformal transformation; Higgs cosmology; cosmology; higgs inflaton; inflaton;

    Sammanfattning : In this project a recent model of inflation in which the Standard Model Higgs field with a nonminimal coupling to gravity takes on the role of the inflaton field is investigated. The tensor to scalar ratio, spectral index and the running of the spectral index  is calculated for a tree level analysis and compared with the Planck experiment. LÄS MER

  3. 17. Lekmäns delaktighet i rättskipningen - En utredning av argumenten för och emot det svenska nämndemannasystemet ur ett rättsutvecklingsperspektiv

    Kandidat-uppsats, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakulteten

    Författare :Edwina Månsson; [2017]
    Nyckelord :Processrätt; Criminal procedure; Straffrätt; Nämndemän; Lay judges; Nämndemannasystemet; Law and Political Science;

    Sammanfattning : Förekomsten av juridiskt oskolade som ett inslag i den dömande verksamheten, är ett fenomen som existerar världen över. I Sverige har institutionen med s.k. nämndemän länge varit en del av rättssystemet. LÄS MER

  4. 18. What can fixit after Brexit? An empirical study of the economic effect on UK trade, following an exit from the European Union

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Sofie Andersson; Frida Nilsson; [2016]
    Nyckelord :Brexit; European Union; the UK; European Economic Area; Trade; Gravity Model; Business and Economics;

    Sammanfattning : One of the most debated political events during 2016 was the referendum regarding the United Kingdom’s future in the European Union. Despite the many warnings received from economists the UK voters voted for ‘leave’, paving the way for Brexit. LÄS MER

  5. 19. On the consistency of multigravity theories

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Marcus Högås; [2016]
    Nyckelord :Gravity; Modified theories for gravity; Bimetric gravity; Multimetric gravity; Bigravity; Multigravity; Consistency; Deser-van Nieuwenhuizen condition; Symmetric vielbein condition; Symmetrization condition;

    Sammanfattning : In this thesis a set of recently proposed multigravity theories is analysed. In the special case of bimetric gravity, the theory has been conclusively shown to be ghost-free. On the other hand, for multigravity theories in general, the ghost-issue has not been settled conclusively. LÄS MER

  7. 20. Tuition fees and student mobility

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Jiexi Yang; Yiran Wang; [2016]
    Nyckelord :tuition fees; student mobility; gravity model; Business and Economics;

    Sammanfattning : The upsurge in the popularity of studying abroad continues across the globe. By adopting the context of human capital migration theory, our paper aims to examine how tuition fees influences international student mobility. LÄS MER
