Second boundary value problem for the Hessian curvature flow

Rongli Huang, Changzheng Qu, Zhizhang Wang +1

We investigate the evolution of strictly convex hypersurfaces driven by the $k$ -Hessian curvature flow, subject to the second boundary condition. We first explore the translating s…

Hessian curvature hypersurfaces with prescribed Gauss image

Huang Rongli, Qu Changzheng, Wang Zhizhang +1

In this paper, we investigate Hessian curvature hypersurfaces with prescribed Gauss images. Given geodesically strictly convex bounded domains $I^c ◯$ in $R^{n}$ and $I^~ c ◯$ …

Translating solutions and the entire Hessian curvature flow in Minkowski space

Qu Changzheng, Wang Zhizhang, Wo Weifeng

In this paper, we study the $k$ -Hessian curvature flow of noncompact spacelike hypersurfaces in Minkowski space. We first prove the existence of translating solutions with given as…
