We prove invarianceunder isometries, continuity, and completeness in the generic case, which are necessary featuresfor the reliable comparison of crystals. The proof of continuity integrates methods from discretegeometry and lattice theory, while the proof of generic completeness combines techniques fromgeometry with analysis. The fingerprint has a fast algorithm based on Brillouin zones and relatedinclusion-exclusion formulae. We have implemented the algorithm and describe its application tocrystal structure prediction.","lang":"eng"}],"department":[{"_id":"HeEd"}],"day":"02","file":[{"content_type":"application/pdf","access_level":"open_access","creator":"mwintrae","file_name":"df_socg_final_version.pdf","checksum":"1787baef1523d6d93753b90d0c109a6d","relation":"main_file","success":1,"file_id":"9346","file_size":3117435,"date_created":"2021-04-22T08:08:14Z","date_updated":"2021-04-22T08:08:14Z"}],"type":"conference","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_updated":"2023-02-23T13:55:40Z","month":"06","article_processing_charge":"No"}
