Computation of generalized Killing spinors on reductive homogeneous spaces
Andree Lischewski
We determine the holonomy of generalized Killing spinor covariant derivatives of the form on pseudo-Riemannian reductive homogeneous spaces in a purely algebraic an…

Conformal superalgebras via tractor calculus
Andree Lischewski
We use the manifestly conformally invariant description of a Lorentzian conformal structure in terms of a parabolic Cartan geometry in order to introduce a superalgebra structure o…

Reducible conformal holonomy in any metric signature and application to twistor spinors in low dimension
Andree Lischewski
We prove that given a pseudo-Riemannian conformal structure whose conformal holonomy representation fixes a totally lightlike subspace of arbitrary dimension, there is, wrt. a loca…
