Homometric model sets and window covariograms
Michael Baake, Uwe Grimm
Two Delone sets are called homometric when they share the same autocorrelation or Patterson measure. A model set LAMBDA within a given cut and project scheme is a Delone set that i…
A radial analogue of Poisson's summation formula with applications to powder diffraction and pinwheel patterns
Michael Baake, Dirk Frettlöh, Uwe Grimm
Diffraction images with continuous rotation symmetry arise from amorphous systems, but also from regular crystals when investigated by powder diffraction. On the theoretical side,…
Pinwheel patterns and powder diffraction
Michael Baake, Dirk Frettlöh, Uwe Grimm
Pinwheel patterns and their higher dimensional generalisations display continuous circular or spherical symmetries in spite of being perfectly ordered. The same symmetries show up…
Surprises in approximating Levenshtein distances
Michael Baake, Uwe Grimm, Robert Giegerich
The Levenshtein distance is an important tool for the comparison of symbolic sequences, with many appearances in genome research, linguistics and other areas. For efficient applica…
