DESCRIPTION:Few examples of extended TQFTs are known explicitly. In this t
 alk I will discuss a very explicit construction of the extended TQFTs asso
 ciated to Rozanksy-Witten models with affine target spaces. I will further
 more explain how to incorporate defects into the extended TQFTs. This can 
 be used for instance to derive the Hilbert spaces of affine Rozansky-Witte
 n models associated to surfaces with arbitrary insertions of defect networ
 ks.
