  1. 1. A CURRENCY UNION’S EFFECT ON INTERNATIONAL TRADE - EMU membership effect on international trade for Slovenia, Cyprus, Malta and Slovakia

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

    Författare :John Elveljung; Stina Oad; [2019-02-15]
    Nyckelord :Common currency areas; Currency union; Optimal Currency Area; EMU; EU; Export; Gravity Model; International rate;

    Sammanfattning : This thesis investigates if there is an increase in international trade from joining a currency union. This is done by looking at the European Monetary Union with a focus on four countries that became members in 2007-2009: Slovenia, Cyprus, Malta and Slovakia. LÄS MER

  2. 2. Asymptotic Symmetries and Faddeev-Kulish states in QED and Gravity

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :David Gaharia; [2019]
    Nyckelord :Faddeev-Kulish; BMS; Bondi-Metzner-Sachs; Asymptotic Symmetries; Asymptotic States; Wilson Lines; Infrared Divergence; Bloch-Nordsieck; Large Gauge Transformations; Fock; QED; Quantum Electrodynamics; Perturbative Quantum Gravity; PQG; U 1 ; Transformations; Mandelstam Quantization;

    Sammanfattning : When calculating scattering amplitudes in gauge and gravitational theories one encounters infrared (IR) divergences associated with massless fields. These are known to be artifacts of constructing a quantum field theory starting with free fields, and the assumption that in the asymptotic limit (i.e. LÄS MER

  3. 3. Galaxy clusters and cosmic voids in modified gravity scenarios

    L3-uppsats, Uppsala universitet/Teoretisk astrofysik

    Författare :Sveva Castello; [2019]
    Nyckelord :Cosmology; galaxy clusters; cosmic voids; f R gravity;

    Sammanfattning : The so-called 'cosmic web', comprising cosmic voids and galaxy clusters, has been proven to be extremely sensitive to deviations from General Relativity. This could be further investigated by future large-scale surveys, such as with the European Space Agency satellite Euclid. LÄS MER

  4. 4. Effect of chameleons on the mass of a galaxy cluster

    Master-uppsats, Uppsala universitet/Teoretisk astrofysik

    Författare :Isabel Roca Vich; [2019]
    Nyckelord :Chameleons; modified gravity; galaxy cluster;

    Sammanfattning : Chameleons are scalar fields coming from modied gravity theories and can be possible explanations for Dark Energy. They cause a fifth force and have a screening mechanism which allows this force to avoid solar system constraints. In this thesis, astrophysical consequences of the potential presence of the chameleon field will be studied. LÄS MER

  5. 5. Valutors betydelse för internationell handel under tider av kris

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Gabriel Bladh; Hanna Kanon; [2019]
    Nyckelord :Euro; Crisis; Currency Union; EU; Trade; Business and Economics;

    Sammanfattning : This paper aims to analyze trade dynamics in the EU-area following the financial crisis of 2007/2008. Our goal has been to investigate whether there is any difference between eu-romember countries and non-euromember countries when it comes to trade in the aftermath of the crisis. LÄS MER
