Melbourne, Roberto
Quantiative form of Ball's cube slicing in R^n and equality cases in min-entropy power inequality. Proc. Amer. Math. Soc. 150 (2022), no. 8, 3595–3611.
NB: As pointed out to us by Tomasz Tkocz there is a small error in the proof of Theorem 2. At the top of page 3601 we argue that I(a_{j_o}) \leq \sqrt{2}, an inequality which might be wrong. However, by a continuity argument it is not difficult to proove that I(a_{j_o}) cannot be much larger than \sqrt{2} which allows one to continue the proof at the only price of some constants.
