A universal scaling function for giant graviton OPE coefficients
Miao He, Yunfeng Jiang
We consider the large spin limit of the OPE coefficient for two maximal giant gravitons and a spinning operator with finite twist in planar super-Yang-…

The virtual fundamental class for the moduli space of surfaces of general type
Yunfeng Jiang
We prove that the moduli stack of index-one covers of semi-log-canonical surfaces of general type is isomorphic to the KSBA moduli stack of stable general type surfaces. Using the…

Equivariant smoothing of cusp singularities
Yunfeng Jiang
We generalize Looijenga's conjecture for smoothing surface cusp singularities to the equivariant setting. Moreover, we prove that for any cusp singularity which admits a one-parame…
