自相似集的极值点集的豪斯多夫维数

Hausdorff dimension of the set of extreme points of a self-similar set

Andrew Tetenov, Ivan Davydkin

摘要:

若$ R^2$上的收缩相似系统S满足开凸集条件,则其不变自相似集K的凸包$\tilde{K}$的极值点集F具有豪斯多夫维数0 .另外,如果相似点的所有旋转角都可以用$π$表示,则集合F是有限的,并且凸包$\tilde{K}$是凸多边形。

英文摘要:

If the system S of contracting similitudes on $ R^2$ satisfies open convex set condition, then the set F of extreme points of the convex hull $\tilde{K}$ of it's invariant self-similar set K has Hausdorff dimension 0 . If, additionally, all the rotation angles of the similitudes are commensurable with $π$, then the set F is finite and the convex hull $\tilde{K}$ is a convex polygon.
