对于每个正整数k,复数在基-k+ i中的基数表示在平面中产生格自仿射瓦片T,其由可以以形式∑j≥1dj(-k+i)-j表示的所有复数组成,其中dj ∈{0,1,2,.,k2}。我们证明了Tk同胚于闭单位圆盘{z∈C:<$z <$$> ≤ 1}当且仅当k <$2.
For each positive integerk, the radix representation of the complex numbers in the base –k+igives rise to a lattice self-affine tileTkin the plane, which consists of all the complex numbers that can be expressed in the form ∑j≥1dj(–k+i)–j, wheredj∈{0, 1, 2, ...,k2}. We prove thatTkis homeomorphic to the closed unit disk {z∈C:∣z∣ ≤ 1} if and only ifk≠ 2.
