On a class of twistorial maps

Abstract

We show that a natural class of twistorial maps gives a pattern for apparently different geometric maps, such as, $(1,1)$-geodesic immersions from $(1,2)$-symplectic almost Hermitian manifolds and pseudo horizontally conformal submersions with totally geodesic fibres for which the associated almost CR-structure is integrable. Along the way, we construct for each constant curvature Riemannian manifold $(M,g)$, of dimension $m$, a family of twistor spaces $\{Z_r(M){\}}_{1\le r<\frac{1}{2}m}$ such that $Z_r(M)$ parametrizes naturally the set of pairs $(P,J)$, where $P$ is a totally geodesic submanifold of $(M,g)$, of codimension $2r$, and $J$ is an orthogonal complex structure on the normal bundle of $P$ which is parallel with respect to the normal connection.
