Resurgence through Dyson-Schwinger Equations

After a brief review of Dyson-Schwinger equations, I will discuss whether and how these equations may serve as a potential source of resurgence for perturbative quantum field theory. Although my latest pertinent results in Yukawa theory and quantum electrodynamics are negative for a fairly generic transseries ansatz, I contend that there are signs of resurgence that should, at least in principle, hold for a much wider class of resurgent transseries. Finally, I will go on to consider the possible role played by renormalisation and specific transmonomials to encode nonperturbative quantum states.
