摘要:

本文研究了定义在双曲平面$\mathscr{H}^{n}(1)$上的凸片上的类空图超曲面在$(n+1)$维Lorentz-Minkowski空间$\mathbb{R}^{n+1}_{1}$中沿着Neumann边界条件为零的各向异性逆中曲率流的演化,并证明了这种流的存在性.此外,我们可以证明,经过适当的重新缩放,不断发展的类空图形超曲面光滑收敛到一个双曲平面的中心在原点和规定的半径,这实际上对应于一个常数函数定义在片的$\mathscr{H}^{n} (1)$,随着时间趋于无穷大。显然,这个结论是我们以前工作的扩展[2]。

英文摘要:

In this paper, we consider the evolution of spacelike graphic hypersurfaces defined over a convex piece of hyperbolic plane $\mathscr{H}^{n}(1)$, of center at origin and radius $1$, in the $(n+1)$-dimensional Lorentz-Minkowski space $\mathbb{R}^{n+1}_{1}$ along an anisotropic inverse mean curvature flow with the vanishing Neumann boundary condition, and prove that this flow exists for all the time. Moreover, we can show that, after suitable rescaling, the evolving spacelike graphic hypersurfaces converge smoothly to a piece of hyperbolic plane of center at origin and prescribed radius, which actually corresponds to a constant function defined over the piece of $\mathscr{H}^{n} (1)$, as time tends to infinity. Clearly, this conclusion is an extension of our previous work [2].
