Simple Wavelet Sets for Scalar Dilations in ℝ2

Part of the Applied and Numerical Harmonic Analysis book series (ANHA)


Wavelet sets for dilation by any scalar d > 1 in L2(ℝ2) are constructed that are finite unions of convex polygons. Such simple wavelet sets for dilation by 2 were widely conjectured to be impossible. The examples are built using the generalized scaling set technique of Baggett et al. [3]. Generalizations to other expansive dilations in L2(ℝ2) are discussed.
