An operator-coefficients free Poincar\'e inequality

Operator Algebras 2023-01-23 v1

Abstract

We prove the following operator-coefficients free Poincar\'{e} inequality: f(X)E[f(X)]22X2^X:B[f(X)]π,f(X)dom(^X:B),|f(X)-E[f(X)]|_{2}\leq2|X|_{2}\|\widehat{\partial}_{X:B}[f(X)]\|_{\pi}, \quad f(X) \in \mathrm{dom}(\widehat{\partial}_{X:B}), where π\|\cdot\|_{\pi} is the projective tensor norm.
