论文摘要
我们提出了两个明确的组合结构，这些结构可有限地总结减少“γ” - 元素$γ_r\，\ in \，kk（c^*_ r（γ），{\ mathbb c}）$ for word-hyyprbolic group $（γ，s）$（γ）$（s）$，并获得$ sumperiation $ bugranity $ supters $ cost $ underbort $ supertion $ costeration $ suption $ selets $ seration $ seration $ serative $ seration $ seration $相关的Cayley图的常数。
We present two explicit combinatorial constructions of finitely summable reduced "Gamma"-elements $γ_r\,\in\,KK(C^*_r(Γ),{\mathbb C})$ for any word-hyperbolic group $(Γ,S)$ and obtain summability bounds for them in terms of the cardinality of the generating set $S\subsetΓ$ and the hyperbolicity constant of the associated Cayley graph.
