Oct 16, 2021 at 8:55 comment added Dima Pasechnik the link to Gromov's paper is broken. What paper is it? numdam.org/item/PMIHES_1982__56__5_0 ?
Sep 4, 2017 at 21:52 comment added Misha @C.F.G: Perelman proved the Poincare conjecture, implying that the only closed simply-connected 3-manifold is $S^3$. Berger spheres indeed show that $S^3$ satisfies Gromov's Minimal Volume Conjecture. (Yes, you can derive this from the existence of a free $S^1$-action as well, but the result was known before Gromov's paper.)

Sep 3, 2017 at 16:43 comment added C.F.G Prof. Gromov in his paper noted that if $M$ admit a locally free $\Bbb S^1$-action then $\min {\rm Vol}(M)=0$. In particular $\min {\rm Vol}(\Bbb S^3)=0$. Does this prove the conjecture in dim $3$?
