Extended 3-dimensional topological field theories

I will survey recent advances in our understanding of extended
3-dimensional topological field theories. I will describe recent work (joint
with B. Bartlett, C. Douglas, and J. Vicary) which gives an explicit
"generators and relations" classification of partially extended 3D TFTS
(assigning values only to 3-manifolds, surfaces, and 1-manifolds). This will
be compared to the fully-local case (which has been considered in joint work
with C. Douglas and N. Snyder).
