摘要
我们考虑Heisenberg 群中的逆均匀曲率流(\Hen,dε),其中 dε 是与 ∣⋅∣ε, ε>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)。对于 Ω⊆\Hen 为开集,其光滑边界 Σ0=∂Ω 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}_{s \geq 0} \subseteq \mathbb{H}^n,thesehypersurfacesarelevelsetsofapropergloballyLipschitzfunctionwithlogarithmicgrowthatinfinity.在Riemannian和亚Riemannian设置下,我们采用Huisken和Ilmanen引入的弱形式,followtheapproachin\citeMoserduetoMoserandbasedonthelinkbetweenIMCFandp−harmonicfunctions.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。
