Abstract

Let (Mn+1,g)(M^{n+1},g) be a closed Riemannian manifold, n+13n+1\geq 3. We will prove that for all mNm \in \mathbb{N}, there exists c(m)>0c^{*}(m)>0, which depends on gg, such that if 0<c<c(m)0<c<c^{*}(m), (M,g)(M,g) contains at least mm many closed cc-CMC hypersurfaces with optimal regularity. More quantitatively, there exists a constant γ0\gamma_0, depending on gg, such that for all c>0c>0, there exist at least γ0c1n+1\gamma_0c^{-\frac{1}{n+1}} many closed cc-CMC hypersurfaces (with optimal regularity) in (M,g)(M,g). This extends the theorem of Zhou and Zhu, where they proved the existence of at least one closed cc-CMC hypersurface in (M,g)(M,g).
