等变η形式正则性的新证明

A new proof of the regularity of equivariant eta form

将等变η形式的定义推广至较一般的紧纤维丛沿纤维方向Clifford代数丛的自伴Clifford模上,给出了一个关于其正则性的新证明.由于将原有定义中纤维奇数的条件推广至任意维数,因而得到更一般的结果.

The author extends the definition of the equivariant eta form to the more general case and gives a new proof of the regularity. In this new definition, the author removes the condition odddimensional fiber in the reference.
