Perturbative quantization of the two-dimensional supersymmetric sigma model
Arnold, Bertram Niklas (2022-03-15)The two-dimensional nonlinear sigma model is a classical field theory whose fields are maps from a Riemann surface Σ to a Riemannian manifold X, and whose classical solutions are minimal surfaces. In this thesis, we study ... -
Vertex Algebras and Factorization Algebras
Brügmann, Daniel Georg (2021-07-19)This thesis is about the relationship between vertex algebras and Costello-Gwilliam factorization algebras, two mathematical approaches to chiral conformal field theory. Many vertex algebras have already been constructed. ...
