abstract
We prove the Geometric P=W conjecture in rank 3 on the three-punctured sphere. We describe the topology at infinity of the related character variety. We use asymptotic abelianization of harmonic bundles away from the ramification divisor and an equivariant approach near the branch points to find the WKB (also known as Liouville--Green or phase-integral) expansion of the involved maps. We analyze the Stokes phenomenon governing their behavior.

Rank three representations of Painleve systems: III. Dolbeault structure, spectral correspondence
Algebraic Nahm transformation gives a holomorphic symplectic isomorphism between the rank-2 and rank-3 (JKT) Dolbeault moduli spaces for all six Painleve systems, realized by explicit elliptic fibrations of types I*_0, I*_1, eE6, eE7, eE8.
