SUMMARY:The Physics of Divergence: Resurgence and Non-Perturbative Phy
 sics\, Physics Department Colloquium\, Gerald Dunne\, University of Co
 nnecticut
DESCRIPTION:Solvable interesting problems in physics are very rare. Al
 most all nontrivial problems require approximations\, the most common 
 of which is perturbation theory. We are all familiar with the basic id
 ea of perturbation theory\, but it holds some surprising secrets\, whi
 ch can be understood physically. These secrets also introduce some nov
 el concepts from a new mathematical formalism called "resurgent asympt
 otics". The talk is largely non-technical\, concentrating on the key p
 hysical ideas and examples\, illustrated with applications in quantum 
 mechanics and quantum field theory.
