真李群胚作用的解析指数

The analytic index for proper, Lie groupoid actions

Alan L. T. Paterson

摘要:

许多指标定理(古典和非交换几何)可以解释为李群胚适当地作用在流形上,并留下一个椭圆族的伪微分算子不变。阿兰·康纳斯(Alain Connes)在他的书中提出了在这种一般情况下的指数定理问题。在本文中,许多这样的情况下,一个分析指数的构建。该方法的灵感来自经典的家庭定理的Atiyah和辛格,和证明推广,适当的李群作用的情况下,一些结果证明适当的局部紧群作用的N。C.菲利浦

英文摘要:

Many index theorems (both classical and in noncommutative geometry) can be interpreted in terms of a Lie groupoid acting properly on a manifold and leaving an elliptic family of pseudodifferential operators invariant. Alain Connes in his book raised the question of an index theorem in this general context. In this paper, an analytic index for many such situations is constructed. The approach is inspired by the classical families theorem of Atiyah and Singer, and the proof generalizes, to the case of proper Lie groupoid actions, some of the results proved for proper locally compact group actions by N. C. Phillips.
