WebIt is classical from Cheeger -Colding that the Hausdorff dimension of Sk satisfies dimSk ≤ k and S = Sn − 2, i.e., Sn − 1 ∖ Sn − 2 = ∅. However, little else has been understood about the structure of the singular set S. Our first result for such limit spaces Xn states that Sk is k -rectifiable for all k.
