Theorem 4.2.6 (Vempala–Wibisono 2019; current Chewi numbering)

Theorem statement
\[\begin{gathered}C_{\mathrm{LSI}}(\pi)\le \alpha^{-1},\quad \nabla V\text{ is }\beta\text{-Lipschitz},\quad h\le (4\beta)^{-1},\\ \operatorname{KL}(\widehat\mu_{Nh}\Vert\pi)\le e^{-\alpha Nh}\operatorname{KL}(\widehat\mu_0\Vert\pi)+O\!\left(\frac{\beta^2dh}{\alpha}\right).\end{gathered}\]
