    A unified flow approach to smooth, even LpL_p-Minkowski problems

    Get PDF
    We study long-time existence and asymptotic behaviour for a class of anisotropic, expanding curvature flows. For this we adapt new curvature estimates, which were developed by Guan, Ren and Wang to treat some stationary prescribed curvature problems. As an application we give a unified flow approach to the existence of smooth, even LpL_p-Minkowski problems in Rn+1\mathbb{R}^{n+1} for p>−n−1.p>-n-1.Comment: 21 pages. Comments are welcom
