Abstract

For the quermassintegral inequalities of horospherically convex hypersurfaces in the (n+1)(n+1)-dimensional hyperbolic space, where n2n\geq 2, we prove a stability estimate relating the Hausdorff distance to a geodesic sphere by the deficit in the quermassintegral inequality. The exponent of the deficit is explicitly given and does not depend on the dimension. The estimate is valid in the class of domains with upper and lower bound on the inradius and an upper bound on a curvature quotient. This is achieved by some new initial value independent curvature estimates for locally constrained flows of inverse type.
