Geometric analysis of the Yang-Mills-Higgs-Dirac model
Jürgen Jost, Enno Keßler, Ruijun Wu +1
The harmonic sections of the Kaluza-Klein model can be seen as a variant of harmonic maps with additional gauge symmetry. Geometrically, they are realized as sections of a fiber bu…

Super Riemann surfaces, metrics, and gravitinos
Jürgen Jost, Enno Keßler, Jürgen Tolksdorf
The underlying even manifold of a super Riemann surface is a Riemann surface with a spinor valued differential form called gravitino. Consequently infinitesimal deformations of sup…
