Three-Way Tiling Sets in Two Dimensions Academic Article uri icon


  • In this article we show that there exist measurable sets W2 with finite measure that tile 2 in a measurable way under the action of a expansive matrix A, an affine Weyl group W and a full rank lattice 2 . This note is follow-up research to the earlier article "Coxeter groups and wavelet sets" by the first and second authors, and is also relevant to the earlier article "Coxeter groups, wavelets, multiresolution and sampling" by M. Dobrescu and the third author. After writing these two articles, the three authors participated in a workshop at the Banff Center on "Operator methods in fractal analysis, wavelets and dynamical systems," December 2-7, 2006, organized by O. Bratteli, P. Jorgensen, D. Kribs, G. lafsson, and S. Silvestrov, and discussed the interrelationships and differences between the articles, and worked on two open problems posed in the Larson-Massopust article. We solved part of Problem 2, including a surprising positive solution to a conjecture that was raised, and we present our results in this article. 2009 Springer Science+Business Media B.V.
