Ultraproducts of crossed product C*algebras

Zhengyu Fu

We study the relationship between the ultraproduct of a crossed product C*algebra $(A ⋊_{r} G)^{I ¨} $ and the crossed product of an ultraproduct C*algebra $A^{I ¨} ⋊_{r} G$ for…

A reverse entropy power inequality for i.i.d. log-concave random variables

Zhen Fu, Jiange Li

We show that $h_{\infty} (X + Y) \leq h_{\infty} (Z + W)$ , where $X, Y$ are independent log-concave random variables, and $Z, W$ are exponential random variables having the same respective $\…
