证明了广义Sierpinski地毯上直到标量倍数时,只存在一个关于地毯局部对称性不变的局部正则Dirichlet形式。因此,对于每一个这样的分形体,布朗运动定律都是唯一确定的,拉普拉斯函数也是明确定义的。
We prove that, up to scalar multiples, there exists only one local regular Dirichlet form on a generalized Sierpinski carpet that is invariant with respect to the local symmetries of the carpet. Consequently for each such fractal the law of Brownian motion is uniquely determined and the Laplacian is well defined.
