黎曼积中具有预定接触角的非参数中曲率流动

Non-parametric mean curvature flow with prescribed contact angle in Riemannian products

Jean-Baptiste Casteras, Esko Heinonen, Ilkka Holopainen, Jorge H. de Lira

摘要:

假设$Ω$中存在速度为$C$的平移孤子$u_\infty$,$\partialΩ$上具有预定的接触角,证明了具有相同预定接触角的中曲率流的图解解收敛于$u_\infty +Ct$为$t\to\infty$ .在适当的$Ω$的凸性和$Ω$的里奇曲率的界的条件下,我们将Gao,Ma,Wang和Weng最近的存在性结果推广到非欧情形.

英文摘要:

Assuming that there exists a translating soliton $u_\infty$ with speed $C$ in a domain $Ω$ and with prescribed contact angle on $\partialΩ$, we prove that a graphical solution to the mean curvature flow with the same prescribed contact angle converges to $u_\infty +Ct$ as $t\to\infty$. We also generalize the recent existence result of Gao, Ma, Wang and Weng to non-Euclidean settings under suitable bounds on convexity of $Ω$ and Ricci curvature in $Ω$.
