Abstract: Very few examples of extended TQFTs are known explicitly. In this talk I will discuss a very explicit construction of the extended TQFTs associated to Rozanksy-Witten models with affine target spaces. I will furthermore explain how to incorporate defects into the extended TQFTs. This can be used for instance to derive the Hilbert spaces of affine Rozansky-Witten models associated to surfaces with arbitrary insertions of defect networks.
