Mirror of Orbifold Singularities in the Hitchin Fibration: the case
Yongbin Ruan, Cheng Shu
We study the geometry of singular -Hitchin fibres over the elliptic locus. We show that orbifold singularities appear in the -moduli space $M^{ell}(\text…

Higher-genus quasimap wall-crossing via localization
Emily Clader, Felix Janda, Yongbin Ruan
We give a new proof of Ciocan-Fontanine and Kim's wall-crossing formula relating the virtual classes of the moduli spaces of -stable quasimaps for different in any genus,…
