Several new two-variable elliptic genera
Yong Wang
In this paper, we define several new two-variable elliptic genera for even dimensional spin manifolds which are the index for some Dirac operators and holomorphic , $Î_0(…
E8 bundles and some new anomaly cancellation formulas
Yong Wang
Using bundles, we construct some new modular forms over , and and get some new anomaly cancellation formulas of characteristic forms which…
Several new Witten rigidity theorems for spin manifolds
Jianyun Guan, Kefeng Liu, Yong Wang
Using Liu's modular invariance method and its odd-dimensional extension by Han and Yu, we establish new Witten rigidity theorems for the generalized Witten genus of twisted Dirac o…
Several new Witten rigidity theorems for elliptic genus
Jianyun Guan, Kefeng Liu, Yong Wang
Using the Liu's method, we prove a new Witten rigidity theorem of elliptic genus of twisted Dirac operators in even dimensional spin manifolds under the circle action. Combined wit…
