对于每一个正整数n,复数在基数-n + i中的基数表示引起平面的平铺。每个图块由所有可以用基数-n + i表示的复数和固定的整数部分组成。我们表明每个瓦片边界的分维为2 log λn/log(n2 + 1),其中λn是λ3 -(2n - 1)λ2 -(n -1)2λ -(n2 + 1)的正根。
Abstract For each positive integer n, the radix representation of the complex numbers in the base —n + i gives rise to a tiling of the plane. Each tile consists of all the complex numbers representable in the base -n + i with a fixed integer part. We show that the fractal dimension of the boundary of each tile is 2 log λn/log(n2 + 1), where λn is the positive root of λ3 - (2n - 1) λ2 - (n - 1) 2λ - (n 2 + 1).
