Title: Wild Higgs Bundles and Modular Categories
Abstract: We propose a new link between the moduli spaces of wild Higgs bundles and quantum invariants of 3manifolds. The construction goes through a class of fourdimensional quantum field theories known as ArgyresDouglas theories. Every such theory realizes a wild Hitchin space as its Coulomb branch and defines a VOA on the Higgs branch. The latter can be used to construct a nonunitary modular tensor category, which leads to 3d TQFTs that are generically semisimple but nonunitary. This is based on joint work with Mykola Dedushenko, Sergei Gukov, Hiraku Nakajima and Ke Ye.
