  1. 6. A classifying algebra for CFT boundary conditions

    Författare :Carl Stigner; Jürgen Fuchs; Alexei Semikhatov; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary conditions; Conformal field theory; Factorization constraints; Modular tensor categories; TFT-construction; Mathematical physics; Matematisk fysik; Physics; Fysik;

    Sammanfattning : Conformal field theories (CFT) constitute an interesting class of twodimensionalquantum field theories, with applications in string theoryas well as condensed matter physics. The symmetries of a CFT can beencoded in the mathematical structure of a conformal vertex algebra. LÄS MER

  3. 7. Quaternionic Transgression in Hyperkähler Geometry

    Författare :Alexei Kotov; Edwin Langmann; Uppsala universitet; []

    Sammanfattning : It is known, that hyperkähler varieties being a special case of Riemann and Kähler manifolds, admit more symmetries. For this reason, all important structures possibly admit hyperkähler generalization. Some of these generalizations make a theme of this thesis. LÄS MER
