论文摘要
我们研究了与双重Vinberg锥相关的半群，并证明了其三重和ol'shanski \uı极地分解。 此外，我们表明，对于圆锥体上规范的riemannian指标，该半群没有收缩特性。
We investigate the semigroup associated to the dual Vinberg cone and prove its triple and Ol'shanski\uı polar decompositions. Moreover, we show that the semigroup does not have the contraction property with respect to the canonical Riemannian metric on the cone.
