Equivariant Yau conjecture for infinitely many invariant minimal hypersurfaces

From papers

Let Mn+1M^{n+1} be a closed Riemannian manifold equipped with a compact Lie group GG acting by isometries, satisfying

3codim(Gx)7xM.3 \leq \operatorname{codim}(G\cdot x) \leq 7 \qquad \forall x\in M.

A closed embedded minimal hypersurface is GG-invariant when it is preserved by the action of GG. Equivariant Yau conjecture. MM contains infinitely many closed embedded minimal GG-hypersurfaces. The assertion is known when RicM>0\operatorname{Ric}_M>0 by equivariant Almgren–Pitts min-max theory, but is open in the stated generality.
