报告摘要:Suppose that K is the attractor of an iterated function system (IFS) on R2. If K is a self-similar or self-affine set, it is known that the group of all isometries on K is finite. In this talk, I will introduce the equivalent conditions for the infiniteness (or finiteness) of the group when K is a bi-Lipschitz IFS fractal. For the finite case, I will talk about how to calculate the size of the group (joint work with Prof. Deng Qi-Rong).
