多项式有界上同调与Novikov猜想
Polynomially bounded cohomology and the Novikov Conjecture
摘要:
利用研究多项式有界上同调的技术,证明了$K_*^t(\ell^1(G))$的装配映射对所有离散群$G$都是有理内射的.这验证了强Novikov猜想的$\ell^1$ -模拟。
英文摘要:
Using techniques developed for studying polynomially bounded cohomology, we show that the assembly map for $K_*^t(\ell^1(G))$ is rationally injective for all finitely presented discrete groups $G$. This verifies the $\ell^1$-analogue of the Strong Novikov Conjecture for such groups.
