“…Since the sets C s are convex minimizers of P(E) − µ s |E| among all E ⊆ C, for s ≥ s * , their boundary is of class C 1,1 [Brézis and Kinderlehrer 1974;Stredulinsky and Ziemer 1997], with curvature at most µ s , and equal to µ s in the interior of C (note that µ s = h C for s ∈ [s * , s * ]). Remark 3.2.…”

“…We may assume that near x, ∂C is the graph of a nonnegative, C 2 and convex function f : B → ‫ޒ‬ where B is an (N − 1)-dimensional ball centered at x. We may as well assume that ∂C s is the graph of f s : B → ‫,ޒ‬ which is C 1,1 [Brézis and Kinderlehrer 1974;Stredulinsky and Ziemer 1997], and also nonnegative and convex. In B, we have f s ≥ f ≥ 0, and…”

“…The existence of isoperimetric regions for any given volume is solved in the context of sets of finite perimeter, see [6,Chapter 1]. Regularity questions have been studied by Gonzalez, Massari and Tamanini [7] and by Stredulinsky and Ziemer [16]. They have proved that a minimizer E satisfies that ∂E ∩ Ω is a smooth hypersurface with constant mean curvature H 0 off of a singular closed set of small Hausdorff dimension.…”

“…∂ Ω is of class C 1,1 , then also ∂C enjoys the same regularity (see [4]); the same result holds if Ω is convex, as a consequence of the results in [21].…”
