Abstract
Let be an -dimensional compact connected manifold with boundary, a constant and an integer. We prove that supports a Riemannian metric with the interior -curvature and the boundary -curvature , if and only if has the homotopy type of a CW complex with a finite number of cells with dimension . Moreover, any Riemannian manifold with sectional curvature and boundary principal curvature is diffeomorphic to the standard closed -ball.
