An Almost Flat Spin Manifold Bounds
Fei Han, Ruizhi Huang, Weiping Zhang
We prove that every almost flat spin^ manifold bounds a compact orientable manifold, thereby settling, in the spin^ case, a long-standing conjecture of Farrell--Zdravkovska a…

Differential Models for the Anderson Dual to Twisted -Bordism and a Twisted Anomaly Map
Fei Han, Yuanchu Li
We construct differential models for degree-3 twisted -bordism and for its Anderson dual. The model for the differential Anderson dual is based on the framework of…
