Specifically, we show that for every polyhedral complex, K, and every dimension, p, there is a partition of the set of p-cells into a maximal p-tree, a maximal p-cotree, and a collection of p-cells whose cardinality is the p-th reduced Betti number of K. Given an ordering of the p-cells, this tri-partition is unique, and it can be computed by a matrix reduction algorithm that also constructs canonical bases of cycle and boundary groups.","lang":"eng"}],"file_date_updated":"2020-11-20T13:22:21Z","date_created":"2020-04-19T22:00:56Z","publication_status":"published","language":[{"iso":"eng"}],"publication":"Discrete and Computational Geometry","_id":"7666","scopus_import":"1","oa":1,"file":[{"file_size":701673,"relation":"main_file","creator":"dernst","file_id":"8786","file_name":"2020_DiscreteCompGeo_Edelsbrunner.pdf","date_updated":"2020-11-20T13:22:21Z","success":1,"content_type":"application/pdf","date_created":"2020-11-20T13:22:21Z","checksum":"f8cc96e497f00c38340b5dafe0cb91d7","access_level":"open_access"}],"publisher":"Springer Nature","day":"20","department":[{"_id":"HeEd"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","isi":1,"article_processing_charge":"Yes (via OA deal)"}
