Daubechies' time-frequency localization operator on Cantor type sets II

We study a version of the fractal uncertainty principle in joint time-frequency representation. Namely, we consider Daubechies' localization operator projecting onto spherically symmetric n-iterate Cantor sets with an arbitrary base M>1 and alphabet A. derive upper bound asymptote up to multiplicative constant for norm terms M size |A| set. For any fixed size, show that there are such is optimal. In particular, precise mid-third set, which was studied part I [19]. Nonetheless, this does not extend every set as provide examples where optimal achieved.
