摘要

我们考虑Heisenberg 群中的逆均匀曲率流(\Hen,dε\He^n, d_\varepsilon),其中 dεd_\varepsilon 是与 ε| \cdot |_\varepsilon, ε>0\varepsilon>0, 由左不变黎曼度量构成的自然家族,或其亚黎曼对应物 (ε=0\varepsilon=0)。对于 Ω\Hen\Omega \subseteq \He^n 为开集,其光滑边界 Σ0=Ω\Sigma_0=\partial \Omega 满足均匀外部仪表球条件且补集有界,我们展示了存在全局弱逆均匀曲率流(generalized hypersurfaces) {Σsε\Sigma^\varepsilon_s}_{s \geq 0} \subseteq \mathbb{H}^n,thesehypersurfacesarelevelsetsofapropergloballyLipschitzfunctionwithlogarithmicgrowthatinfinity.Riemannian和亚Riemannian设置下,我们采用HuiskenIlmanen引入的弱形式,followtheapproachin\citeMoserduetoMoserandbasedonthelinkbetweenIMCFand, these hypersurfaces are level sets of a proper globally Lipschitz function with logarithmic growth at infinity. 在Riemannian 和亚Riemannian 设置下,我们采用Huisken 和Ilmanen 引入的弱形式, follow the approach in \cite{Moser} due to Moser and based on the link between IMCF and pharmonicfunctions.具体地,我们基于IMCF-harmonic functions. 具体地,我们基于IMCF与p$-调和函数之间的关系,构建了该问题的弱解。
