Sierpinski地毯上的调和函数与Laplacian的谱

Harmonic functions and the spectrum of the Laplacian on the Sierpinski carpet

Matthew Begue, Tristan Kalloniatis, Robert S. Strichartz

摘要:

Kusuoka和Zhou利用小单元上函数的平均值和单元邻接的图结构定义了Sierpinski地毯上的Laplacian。我们已经实现了一个算法,使用他们的方法来近似解决边值问题。因此,我们有丰富的数据与规定的边界值的调和函数,和本征函数的拉普拉斯与诺依曼或狄利克雷边界条件。我们将提出一些这样的数据,并讨论一些想法,定义正常的衍生物的边界上的地毯。

英文摘要:

Kusuoka and Zhou have defined the Laplacian on the Sierpinski carpet using average values of functions on small cells and the graph structure of cell adjacency. We have implemented an algorithm that uses their method to approximate solutions to boundary value problems. As a result we have a wealth of data concerning harmonic functions with prescribed boundary values, and eigenfunctions of the Laplacian with either Neumann or Dirichlet boundary conditions. We will present some of this data and discuss some ideas for defining normal derivatives on the boundary of the carpet.
