{"abstract":[{"lang":"eng","text":"We introduce algorithms for the computation of homology, cohomology, and related operations on cubical cell complexes, using the technique based on a chain contraction from the original chain complex to a reduced one that represents its homology. This work is based on previous results for simplicial complexes, and uses Serre’s diagonalization for cubical cells. An implementation in C++ of the introduced algorithms is available at http://www.pawelpilarczyk.com/chaincon/ together with some examples. The paper is self-contained as much as possible, and is written at a very elementary level, so that basic knowledge of algebraic topology should be sufficient to follow it."}],"issue":"1","publication_status":"published","publication":"Advances in Computational Mathematics","quality_controlled":0,"title":"Computation of cubical homology, cohomology, and (co)homological operations via chain contraction","main_file_link":[{"open_access":"1","url":"https://idus.us.es/xmlui/handle/11441/38719"}],"_id":"451","author":[{"id":"3768D56A-F248-11E8-B48F-1D18A9856A87","last_name":"Pilarczyk","full_name":"Pawel Pilarczyk","first_name":"Pawel"},{"full_name":"Real, Pedro","first_name":"Pedro","last_name":"Real"}],"doi":"10.1007/s10444-014-9356-1","intvolume":"        41","extern":1,"type":"journal_article","date_updated":"2021-01-12T07:59:20Z","publist_id":"7371","volume":41,"oa":1,"date_published":"2014-01-01T00:00:00Z","day":"01","publisher":"Kluwer","status":"public","year":"2014","page":"253 - 275","month":"01","date_created":"2018-12-11T11:46:33Z","citation":{"ieee":"P.
