利用非对易几何的工具,我们证明了紧致黎曼流形上从属次拉普拉斯算子的TALAGRAND浓度不等式的一个形式。作为应用,在量子信息论的启发下,我们证明了有限维矩阵代数上满足张量稳定的修正对数Sobolev不等式的自伴生成元集是稠密的。
We prove a version of Talagrand’s concentration inequality for subordinated sub-Laplacians on a compact Riemannian manifold using tools from noncommutative geometry. As an application, motivated by quantum information theory, we show that on a finite-dimensional matrix algebra the set of self-adjoint generators satisfying a tensor stable modified logarithmic Sobolev inequality is dense.
