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.

沉浸网络的各向异性曲率流
我们考虑了由三条曲线的网络的各向异性曲率引起的运动,该曲线浸入了在三重接合处相交的平面中,并且其他端部固定。我们显示了最大几何解的存在性,唯一性和规则性,并且证明了,如果最大时间是有限的,那么其中一条曲线的长度将变为零,或者各向异性的\(L ^ 2 \)-范数曲率炸毁。
