论文摘要
我们研究了热半群的bakry-émery的概括梯度估计值,以及其与热流的某些熵不等式的等效性,用于具有合适群体结构的度量空间的瓦森氏菌测量学。我们的主要结果适用于任何步骤的Carnot组,以及$ \ Mathbb {su}(2)$组。
We study a generalization of the Bakry-Émery pointwise gradient estimate for the heat semigroup and its equivalence with some entropic inequalities along the heat flow and Wasserstein geodesics for metric-measure spaces with a suitable group structure. Our main result applies to Carnot groups of any step and to the $\mathbb{SU}(2)$ group.
