A main interest is to understand the asymptotic behavior of the ows. It was conjectured that the n-power of the Gauss curvature, for > 1 n+2, deforms a convex hypersurface in R +1 into a round point. This is a di cult problem and has been studied by many authors in

Webpowers of the Gauss curvature B Bt F K ~n: We first establish interior estimates for strictly convex solutions by deriving lower bounds for the principal curvatures and upper bounds for the Gauss curvature. We also investigate the opti-mal regularity of weakly convex translating solutions. The interesting case is when the translator has flat ... WebIn this paper we study a normalized anisotropic Gauss curvature flow of strictly convex, closed hypersurfaces in the Euclidean space. We prove that the flow exists for all time …
WebOct 5, 2015 · A similar recent result when H is replaced by the Gauss curvature K, see [9], settled the long standing open problem of whether the flow by certain powers of the … WebWe show that strictly convex surfaces expanding by the inverse Gauss curvature flow converge to infinity in finite time. After appropriate rescaling, they converge to spheres. We describe the algorithm to find our main test function.
