(This question has a physics motivation).
Could we establish any kind of relationship between Super Riemannian manifolds (super Riemannian structures on super manifolds) and Kähler manifolds, or at least, common use of these structures in some context ?
EDIT 1 : There is an article of Edward Witten, Notes On Super Riemann Surfaces And Their Moduli, http://arxiv.org/pdf/1209.2459v4.pdf
EDIT 2 : There is a book, Supergravity, by Daniel Z. Freedman and Antoine Van Proeyen, Cambridge Editions.
Part IV title is "Complex Geometry and SUSY", where SUSY means supersymmetry. Kähler manifolds are used in this part.
