"Complex Submanifolds in Quaternionic Manifolds with Symmetries"

We summarize the basics of the differential geometry of quaternionic structures, and their symmetries. Next we consider examples of structures with large symmetry algebras. In particular we discuss the case of maximal and sub-maximal symmetry dimension. Then we discuss the generalized Feix construction, and how the models and their symmetries arise from this. My results presented in this talk are joint with Boris Kruglikov, Lenka Zalabova, and Aleksandra Borowka.
