Kemperman's inequality and Freiman's lemma via few translates

Yifan Jing, Akshat Mudgal

Let $G$ be a connected compact group equipped with the normalised Haar measure $μ$ . Our first result shows that given $α, β > 0$ , there is a constant $c = c (α, β) > 0$ such that for any…

Measure doubling of small sets in $SO (3, R)$

Yifan Jing, Chieu-Minh Tran, Ruixiang Zhang

Let $SO (3, R)$ be the 3D-rotation group equipped with the real-manifold topology and the normalized Haar measure $μ$ . Resolving a problem by Breuillard and Green,…

Measure growth in compact semisimple Lie groups and the Kemperman Inverse Problem

Yifan Jing, Chieu-Minh Tran

Suppose $G$ is a compact semisimple Lie group, $μ$ is the normalized Haar measure on $G$ , and $A, A^{2} \subseteq G$ are measurable. We show that $$μ(A^2)\geq \min\{1, 2μ(A)+ημ(A)(1-…
