Classification of links with Khovanov homology of minimal rank
Yi Xie, Boyu Zhang
If L is an oriented link with components, then the rank of its Khovanov homology is at least . We classify all the links whose Khovanov homology with Z/2-coefficients achi…

Instanton Floer homology for sutured manifolds with tangles
Yi Xie, Boyu Zhang
We prove an excision theorem for the singular instanton Floer homology that allows the excision surfaces to intersect the singular locus. This is an extension of the non-singular e…
