Local monotonicity of measures supported by graphs of convex functions

Resum: Let f ∈ C2 (R) satisfy f(0) = f 0 (0) = 0 and f 00(0) > 0. Then the 1-dimensional Hausdorff measure restricted to the graph of f is locally monotone near the origin in the sense that there exists σ > 0 such that the function r 7→ µf B(z,r) r is nondecreasing on (0, σ) for every centre z ∈ B(σ). The result is reformulated for Hausdorff measures restricted to uniformly C2 -curves in R 2 with the curvature bounded away from zero and infinity.
