摘要

设$G$是一个线性李群，它在具有紧致商的$G$-自旋$^c$流形$M$上正等距作用。我们证明了Poincare对偶在$G$的$G$-等变$K$-理论和$M$的$G-等变$K$-同调之间成立，这两个理论是用有限维$G$向量丛定义的，这两种理论是用Baum和Douglas的几何模型定义的。

An equivariant Poincaré duality for proper cocompact actions by matrix groups

Let $G$ be a linear Lie group acting properly and isometrically on a $G$-spin$^c$ manifold $M$ with compact quotient. We show that Poincare duality holds between $G$-equivariant $K$-theory of $M$, defined using finite-dimensional $G$-vector bundles, and $G$-equivariant $K$-homology of $M$, defined through the geometric model of Baum and Douglas.
