Gromov's average area ratio conjecture for hyperbolic manifolds
Let be a closed hyperbolic manifold of dimension , and let be a closed -manifold with Riemannian metric whose scalar curvature satisfies . Let be a smooth map of degree . Gromov's conjecture. The average area ratio satisfies
Moreover, equality holds if and only if is a local isometry. This conjecture strengthens Gromov's known lower bound in dimension three from to and proposes the analogous sharp inequality in every dimension ; the supplied context does not state whether it has been resolved.
