1. 1. F-theory on six-dimensional symmetric toroidal orbifolds

   Master-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Finn Bjarne Kohl; [2021]
   Nyckelord :F-theory; orbifolds; String Theory; String Phenomenology; roto-translations; six-dimensional; F-Theorie; Orbifaltigkeiten; String Theorie; String Phenomenologie; Roto-Translationen; sechs-dimensional;

   Sammanfattning : In this thesis, compactifications of F-theory on six dimensional symmetric toroidalorbifolds are explored. These orbifold geometries have been mathematically classified and it is natural to ask what the physical implications of string theorycompactifications on those geometries are. LÄS MER

3. 2. Review of compact spaces for type IIA/IIB theories and generalised fluxes

   L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Panizo Daniel; [2019]
   Nyckelord :supergravity; type IIA; type IIB; compactification; moduli space; T-duality; Buscher rules; six-torus; STU-models;

   Sammanfattning : In the present project we study compactifications of type IIA/IIB string theories on toroidal orbifolds. We present the moduli space for N=1 four-dimensional reductions and its topological properties. To fix the value of all moduli, we will construct the most general holomorphic superpotential W using a set of T-dual iterations for the fluxes. LÄS MER

4. 3. Type IIB compactifications and string dualities

   Master-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Daniel Panizo; [2018]
   Nyckelord :String theory; compactification; dualities;

   Sammanfattning : In the present thesis, we offer an introduction to type IIB string compactifications on $\mathbb{T}^{d}/\Gamma$ toroidal orbifolds. We first describe the technical method to construct these spaces and reduce the string background on it. LÄS MER
