The continuous Babai conjecture for compact simple groups

Let GG be a compact simple group, let rr be the dimension of one of its maximal tori, and let AGA\subset G be a measurable set.

Continuous Babai conjecture. There is an integer mm such that

Am=G,A^m=G,

with

m=O ⁣(logμG(A)rG),m=O\!\left(\frac{\log\mu_G(A)}{r_G}\right),

where the implied constants do not depend on GG.

This is presented as a continuous analogue of Babai's conjecture for finite simple groups in the unbounded-rank setting. The source does not provide evidence of a resolution for this formulation.
