Title: Asymptotic limits in class-S theories and non-Abelian Hodge theory
Abstract: I will discuss a non-Abelian Hodge-theoretic refinement of weak-coupling limits in type-A class-S theories. The construction combines the geometry of a degenerating Riemann surface with flat-connection data on the resulting long tubes. A regular-singular local model describes power-law and logarithmic behavior of flat-section transport, while monodromy data provide coarse discrete labels that enrich the description of weak-coupling cusps. I will illustrate the construction on a four-punctured sphere and a two-punctured torus.
