Unfolding of wild character varieties
Kazuki Hiroe, Daisuke Yamakawa
In this paper, we study wild character varieties on compact Riemann surfaces and construct Poisson maps from wild to tame character varieties by unfolding irregular singularities i…

Wild genus-zero quantum de Rham spaces
Matthew Chaffe, Gabriele Rembado, Daisuke Yamakawa
The wild de Rham spaces parameterize isomorphism classes of (stable) meromorphic connections, defined on principal bundles over wild Riemann surfaces. Working on the Riemann sphere…

Twisted local G-wild mapping class groups
Jean Douçot, Gabriele Rembado, Daisuke Yamakawa
We consider the isomonodromic deformations of irregular-singular connections defined on principal bundles over complex curves: for any complex reductive structure group G, and any…
