This is joint work with Matt Turner (Bath).

This is joint work with Michael Hallam.

This is a joint work with Kenshiro Tashiro, Mattia Magnabosco, and Tommaso Rossi.

We will introduce a similar class of augmented bundles over a topological surface that we call Fock bundles which does not require fixing any complex structure on the underlying surface. We conjecture that there is an alternative passage to the one given by the non-abelian Hodge correspondence from such pairs to certain higher rank Teichmüller spaces that is independent of the complex structure on the surface.

This is joint work with Charles Reid (Austin) and Alexander Thomas (Heidelberg).
