Mediterranean Journal of Mathematics, 18 (2), 43/1-43/15.1660-5446https://hdl.handle.net/11441/110821In this note, we provide an algorithm that, starting with a Sullivan algebra gives us its minimal model. More concretely, taking as input a (nonminimal) Sullivan algebra A with an ordered finite set of generators preserving the filtration defined on A, we obtain as output a minimal Sullivan algebra with the same rational cohomology as A. This algorithm is a kind of modified AT-model algorithm used, in the past, to compute a chain contraction providing other kinds of topological information such as (co)homology, cup products on cohomology and persistent homology.application/pdf15engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Sullivan algebrasMinimal modelsChain homotopyChain contractionsAT-modelinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1007/s00009-020-01670-9
