DESCRIPTION:Speakers: Bercel Boldis (Budapest University of Technology and
  Economics)\n\nIn holographic dualities\, non-perturbative contributions a
 t large ’t Hooft coupling play an important role\, as they encode differ
 ent saddle point corrections for the string worldsheet. Recent work has es
 tablished a systematic method for computing strong-coupling transseries to
  arbitrary order for a class of observables in four-dimensional planar N=2
  and N=4 supersymmetric Yang–Mills theories. These observables can be ex
 pressed in terms of Fredholm determinants at arbitrary ’t Hooft coupling
 .Building on these developments\, I investigate the strong-coupling expans
 ion of observables within this framework\, including the octagon form fact
 or and the cusp anomalous dimension. I present a universal structure gover
 ning their non-perturbative corrections\, which enables the reconstruction
  of their full transseries from perturbative data alone. I also explore re
 surgence relations between non-perturbative sectors and show how the large
 -order behaviour of each sector encodes subleading exponential corrections
