Unformatted text preview: S , what is the shape resulting if T2 and T3 are never applied? Prob 2.4.9 Deﬁne T : K(R2 ) → K(R2 ) by T (A) = {(2x, 2y ) : (x, y ) ∈ A}. Is T continuous in the Hausdorﬀ metric? That is, for every A ∈ K(R2 ) and every ǫ > 0, ﬁnd a δ > 0 for which h(A, B ) < δ implies h(T (A), T (B )) < ǫ. If T is not continuous, ﬁnd a speciﬁc C ∈ K(R2 ) at which continuity fails. Prob 2.4.10 For T1 , T3 and T4 of (2.10), ﬁnd T2 so the attractor of the IFS {T1 , T2 , T3 , T4 } is the unit square, and the region with address 21 is as shown in Fig. 2.31 Prob 2.4.11 Recall Λ(A) denotes the set of limit points of A. For all sets A, B ⊆ R, prove Λ(A ∩ B ) = Λ(A) ∩ Λ(B ), or ﬁnd a counterexample. 2.5 Faster than random: de Bruijn sequences We have seen that the random IFS algorithm eventually will generate points in all regions of length n addresses for any given n, but how much time is needed for “eventually”? For example, if the image is contained in 1024 × 1024 pixels, and is generated by transformations (2.10), then a single pixel has address about 64 CH...
