Title: Topological Applications of Integral TQFT


abstract:
We will discus some applications of the TQFT defined over a cyclotomic  
ring of integers that we have been studying with Gregor Masbaum. These  
include a lower bound for the Heegaard genus of a 3-manifold in terms  
of the ideal generated by the quantum invariants of all links in that  
3-manifold. I will also discuss obstructions to embedding and periodic  
actions.
