Web28 Feb 2014 · In this brief note we study how the fractional mean curvature of order s ∈ ( 0, 1) varies with respect to C 1, α diffeomorphisms. We prove that, if α > s, then the variation under a C 1, α diffeomorphism Ψ Ψ of the s -mean curvature of a set E is controlled by the C 0, α norm of the Jacobian of Ψ Ψ . When α = 1 we discuss the ... WebC. Imbert (Paris-Dauphine) Fractional mean curvature PIMS July 2009 8 / 37.
