Lagrangian correspondences for moduli spaces of Higgs bundles and holomorphic connections
Panagiotis Dimakis, Duong Dinh, Shengjing Xu
On a compact connected Riemann surface of genus at least , we construct Lagrangian correspondences between moduli spaces of rank- Higgs bundles (respectively, holomorphic…

Rank-2 wobbly bundles from special divisors on spectral curves
Duong Dinh
We study rank-2 wobbly bundles on a Riemann surface of genus , i.e. semi-stable bundles admitting nonzero nilpotent Higgs fields, in terms of direct images of line bun…
