分形插值函数的能量与Laplacian

Energy and Laplacian of Fractal Interpolation Functions

Xiao-Hui Li, Huo-Jun Ruan

摘要:

本文首先刻画了后临界有限自相似集上分形插值函数的有限性。然后研究了Sierpinski垫片(SG)上具有均匀垂直尺度因子的分形插值函数的拉普拉斯算子。作为应用,我们证明了SG上的狄利克雷问题的解是一个具有一致垂直尺度因子$\frac{1}{5}$的FIF:$Δu=0$在$SG\setminus \{q_1,q_2,q_3\}$上,且有$u(q_i)=a_i$,$i=1,2,3$,其中$q_i$,$i=1,2,3$是SG的边界点.

英文摘要:

In this paper, we first characterize the finiteness of fractal interpolation functions (FIFs) on post critical finite self-similar sets. Then we study the Laplacian of FIFs with uniform vertical scaling factors on Sierpinski gasket (SG). As an application, we prove that the solution of the following Dirichlet problem on SG is an FIF with uniform vertical scaling factor $\frac{1}{5}$: $Δu=0$ on $SG\setminus \{q_1,q_2,q_3\}$, and $u(q_i)=a_i$, $i=1,2,3$, where $q_i$, $i=1,2,3$, are boundary points of SG.
