等变椭圆上同调与刚性

Equivariant Elliptic Cohomology and Rigidity

Ioanid Rosu

摘要:

复系数等变椭圆上同调由Ginzburg,Kapranov和Vasserot公理化地定义,并由Grojnowski构造。给出了S^1-等变椭圆上同调的一个不变定义,并利用它给出了Witten关于椭圆亏格的刚性定理的一个完全上同调证明。我们还陈述并证明了椭圆族的一个刚性定理。

英文摘要:

Equivariant elliptic cohomology with complex coefficients was defined axiomatically by Ginzburg, Kapranov and Vasserot and constructed by Grojnowski. We give an invariant definition of S^1-equivariant elliptic cohomology, and use it to give an entirely cohomological proof of the rigidity theorem of Witten for the elliptic genus. We also state and prove a rigidity theorem for families of elliptic genera.
