Second variation for L-minimal Legendrian submanifolds in pseudo-Sasakian manifolds
David Petrecca, Lars Schäfer
In this paper we provide a second variation formula for L-minimal Lagrangian submanifolds in a pseudo-Sasakian manifold. We apply it to the case of Lorentzian-Sasakian manifolds an…
On the structure of nearly pseudo-Kähler manifolds
Lars Schäfer
Firstly we give a condition to split off the K"ahler factor from a nearly pseudo-K"ahler manifold and apply this to get a structure result in dimension 8. Secondly we extend the co…
Nearly pseudo-Kähler and nearly para-Kähler six-manifolds
Lars Schäfer, Fabian Schulte-Hengesbach
The subject of this paper is six-dimensional nearly (para-)Kähler geometry with pseudo-Riemannian metrics. Firstly, we derive the analogue of the well-known exterior differential s…
Half-flat Structures and Special Holonomy
Vicente Cortés, Thomas Leistner, Lars Schäfer +1
It was proven by Hitchin that any solution of his evolution equations for a half-flat SU(3)-structure on a compact six-manifold M defines an extension of M to a seven-manifold with…
