具有分形曲率的凸曲面

A Convex Surface with Fractal Curvature

Iancu Dima, Rachel Popp, Robert S. Strichartz, Samuel C. Wiese

摘要:

我们构造了一个表面,该表面是从八面体通过推出4个面而获得的,使得曲率在每个面中的Sierpinski垫片的副本中得到支持,并且本质上是SG上的自相似测度。然后,我们使用表面多面体近似的有限元法计算相关拉普拉斯算子的谱底,并推测整个谱的行为。

英文摘要:

We construct a surface that is obtained from the octahedron by pushing out 4 of the faces so that the curvature is supported in a copy of the Sierpinski gasket in each of them, and is essentially the self similar measure on SG. We then compute the bottom of the spectrum of the associated Laplacian using the finite element method on polyhedral approximations of our surface, and speculate on the behavior of the entire spectrum.
