Height estimate and slicing formulas in the Heisenberg group
Published 7 Oct 2014 in math.CA | (1410.1763v1)
Abstract: We prove a height-estimate (distance from the tangent hyperplane) for $\Lambda$-minima of the perimeter in the sub-Riemannian Heisenberg group. The estimate is in terms of a power of the excess ($L2$-mean oscillation of the normal) and its proof is based on a new coarea formula for rectifiable sets in the Heisenberg group.
