摘要

我们考虑一个由三条曲线组成的网络的各向异性曲率的运动,这三条曲线在平面上以三结点相交,另一端固定。证明了极大几何解的存在性、唯一性和正则性,并证明了如果极大时间是有限的,则要么其中一条曲线的长度趋近于零,要么各向异性曲率的\(L^2\)范数爆发。

Anisotropic Curvature Flow of Immersed Networks

We consider motion by anisotropic curvature of a network of three curves immersed in the plane meeting at a triple junction and with the other ends fixed. We show existence, uniqueness and regularity of a maximal geometric solution and we prove that, if the maximal time is finite, then either the length of one of the curves goes to zero or the \(L^2\)-norm of the anisotropic curvature blows up.

期刊介绍: Milan Journal of Mathematics (MJM) publishes high quality articles from all areas of Mathematics and the Mathematical Sciences. The authors are invited to submit "articles with background", presenting a problem of current research with its history and its developments, the current state and possible future directions. The presentation should render the article of interest to a wider audience than just specialists. Many of the articles will be "invited contributions" from speakers in the "Seminario Matematico e Fisico di Milano". However, also other authors are welcome to submit articles which are in line with the "Aims and Scope" of the journal.
