Dirac-harmonic maps from manifolds with boundary via index theory
Volker Branding, Nicolas Ginoux
Dirac-harmonic maps are a mathematical version of the supersymmetric non-linear sigma model of quantum field theory. Since they arise as critical points of an unbounded energy func…

On the conformal-biharmonic stability of the identity map of Einstein manifolds
Volker Branding, Simona Nistor, Cezar Oniciuc
The identity map of an Einstein manifold is a critical point of both the classical energy functional and the conformal-bienergy functional. In this paper, we investigate the confor…
