From harmonic maps to the nonlinear supersymmetric sigma model of quantum field theory. At the interface of theoretical physics, Riemannian geometry and nonlinear analysis
Jürgen Jost, Enno Keßler, Jürgen Tolksdorf +2
Harmonic maps from Riemann surfaces arise from a conformally invariant variational problem. Therefore, on one hand, they are intimately connected with moduli spaces of Riemann surf…
Partial Regularity for a Nonlinear Sigma Model with Gravitino in Higher Dimensions
Jürgen Jost, Ruijun Wu, Miaomiao Zhu
We study the regularity problem of the nonlinear sigma model with gravitino fields in higher dimensions. After setting up the geometric model, we derive the Euler--Lagrange equatio…
Symmetries and conservation laws of a nonlinear sigma model with gravitino
Jürgen Jost, Enno Keßler, Jürgen Tolksdorf +2
We show that the action functional of the nonlinear sigma model with gravitino considered in a previous article [18] is invariant under rescaled conformal transformations, super We…
Energy quantization for a nonlinear sigma model with critical gravitinos
Jürgen Jost, Ruijun Wu, Miaomiao Zhu
We study some analytical and geometric properties of a two-dimensional nonlinear sigma model with gravitino which comes from supersymmetric string theory. When the action is critic…
Coarse Regularity of Solutions to a Nonlinear Sigma-model with~~gravitino
Jürgen Jost, Ruijun Wu, Miaomiao Zhu
The regularity of weak solutions of a two-dimensional nonlinear sigma model with coarse gravitino is shown. Here the gravitino is only assumed to be in for some . The pr…
