> Mithat Unsal (NCSU): Aspects of resurgence and Picard-Lefchetz theory in QFT
> 
> Abstract:
> 
> Recent works show that there may indeed exist a
> non-perturbative continuum definition of quantum field theory (QFT),
> at least in some interesting regimes.
> I will describe some new ideas from mathematics and physics,
> in particular, the  resurgence theory, the trans-series framework from
> mathematics and the idea of adiabatic continuity from physics to provide new insigths
> into the structure of general QFTs.  The new techniques allow us to
> determine new saddle points which play important dynamical roles, e.g.  in confinement,
> theta-dependence in semi-classically calculable domains. It also
> provides new insights into the nature of IR-renormalon problem. In a
> wide class of quantum mechanical systems, these techniques show that
> all non-perturbative data is secretly encoded in perturbation theory.
