Geometric analysis of the nonlinear sigma model with gravitino
A talk in the Keine Reihe series by
Ruijun Wu from Max-Planck-Institut, Leipzig
| Abstract: |
This model comes from supersymmetric nonlinear sigma models in super string theory and is an extension of the Dirac-harmonic maps. The Dirac operator here is defined along a map from a Riemann surface into a Riemannian manifold. We combine the theories/tools for harmonic maps and for Dirac operators to get a understanding of this model. The gravitino couples the matter fields in a nonlinear way and we cope with this using some recent analysis methods.
