We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

The maximum principle and the Dirichlet problem for Dirac-harmonic maps
Qun Chen, Jürgen Jost and Guofang Wang
Abstract
We establish a maximum principle and uniqueness for Dirac-harmonic maps from a Riemannian spin manifold with boundary into a regular ball in any Riemannian manifold $N$. Then we prove an existence theorem for a boundary value problem for Dirac-harmonic maps.
