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 isomonodromic-deformation parameters of irregular-singular connections on principal G-bundles over complex projective curves: for any connected reductive G, pole order,…
Symmetries of Quiver Schemes
Ryo Terada, Daisuke Yamakawa
We introduce reflection functors on quiver schemes in the sense of Hausel--Wong--Wyss, generalizing those on quiver varieties. Also we construct some isomorphisms between quiver sc…
