Let S be a compact oriented finite dimensional manifold and M a finite dimensional Riemannian manifold, let Immf(S,M) the space of all free immersions φ:S→M and let B+i,f(S,M) the quotient space Immf(S,M)/Diff+(S), where Diff+(S) denotes the group of orientation preserving diffeomorphisms of S. In this paper we prove that if M admits a parallel r-fold vector cross product χ∈Ωr(M,TM) and dimS=r−1 then B+i,f(S,M) is a formally Kähler manifold. This generalizes Brylinski’s, LeBrun’s and Verbitsky’s results for the case that S is a codimension 2 submanifold in M, and S=S1 or M is a torsion-free G2-manifold respectively.
