Description
Purpose of this Workshop:
Perturbation theory is a critically important tool in all areas of
theoretical physics, but it has long been known that it typically produces
divergent asymptotic series, and understanding how to treat such series
fully systematically has been a major challenge. In the last few years
there has been major progress in understanding these issues in the context
of matrix models, string theory, quantum field theory and also quantum
mechanics. Using ideas from resurgence theory, the burst of activity in
this area over the last few years has vividly illustrated the remarkable
fact that the divergences of perturbative series are not at all random,
and contain precise quantitative information about non-perturbative
effects. These developments are leading to deep insights about
non-perturbative structure and dynamics of quantum field theories, such as
insight into the infrared renormalon problem, and non-perturbative
completion in string theories. Conversely, QFT has provided new insight
into the practical implementation of the very widely applicable theory of
resurgence in ways not previously realised by analysts. Novel applications
of resurgence theories being developed include applications to matrix
Riemann Hilbert problems, and through these to integrable nonlinear
systems, orthogonal polynomials, random matrix and knot theories.
