The asymptotic volume growth conjecture under positive scalar curvature

From papers

Let (Mn,g)(M^n,g) be a complete non-compact Riemannian manifold with Ricci curvature Rc0Rc\geq 0. Denote by Bp(r)B_p(r) the open geodesic ball centered at pMnp\in M^n with radius r>0r>0, and by V(Bp(r))V(B_p(r)) its volume. Let RR denote the scalar curvature.

Asymptotic volume growth conjecture. There is a universal constant C(n)>0C(n)>0 such that, if R2R\geq 2, then

limrV(Bp(r))rn2C(n),pMn.\varlimsup_{r\rightarrow\infty}\frac{V(B_p(r))}{r^{n-2}}\leq C(n),\qquad\forall p\in M^n.

This is an asymptotic version of Gromov's volume conjecture, asserting an rn2r^{n-2} upper bound only at infinity rather than uniformly over all radii and centers. The source presents it as a conjecture and gives no resolution status.
