Unformatted text preview: n TB and add a reflection across the x-axis in TC . The bottom middle image of Fig. 2.61 is the attractor of the IFS {TA , TB , TC }, certianly a dendrite, and now containing the points (3/4, 1/2) and (1/2, 3/4). The top middle image of Fig. 2.61 is the attractor of the IFS {TA , TB , TC , TD }, clearly multiply-connected. PrxsSol 2.9.3 From our experience in the first two practice problems, we start with a three function IFS with a totally disconnected attractor. For example, the bottom right image of Fig. 2.61, where TA includes rotation by π/2, TB reflection across the y -axis, and TC rotation by −π/2. To break apart TC (S ) and TD (S ), include a reflection across the y -axis in TD . The attractor of the four function IFS, the top right image of Fig. 2.61, certainly is disconnected. But is it totally disconnected? No line segments are obvious, but perhaps some pieces are connected by curves. This is an interesting problem. 95 2.9.
