Assuming that Y is d-connected and dimX≤2d, for some d≥1, we provide an algorithm that computes the set of all equivariant homotopy classes of equivariant continuous maps |X|→|Y|; the existence of such a map can be decided even for dimX≤2d+1. This yields the first algorithm for deciding topological embeddability of a k-dimensional finite simplicial complex into Rn under the condition k≤23n−1. More generally, we present an algorithm that, given a lifting-extension problem satisfying an appropriate stability assumption, computes the set of all homotopy classes of solutions. This result is new even in the non-equivariant situation.","lang":"eng"}],"oa":1,"date_published":"2017-06-01T00:00:00Z","oa_version":"Submitted Version","publist_id":"6309","type":"journal_article","publisher":"Springer","_id":"1073","year":"2017","doi":"10.1007/s00454-016-9855-6","quality_controlled":"1","author":[{"full_name":"Čadek, Martin","first_name":"Martin","last_name":"Čadek"},{"full_name":"Krcál, Marek","id":"33E21118-F248-11E8-B48F-1D18A9856A87","last_name":"Krcál","first_name":"Marek"},{"last_name":"Vokřínek","first_name":"Lukáš","full_name":"Vokřínek, Lukáš"}],"external_id":{"isi":["000400072700008"]},"date_updated":"2023-09-20T12:01:28Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","status":"public","isi":1,"publication_status":"published","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1307.6444"}],"volume":54,"citation":{"mla":"Čadek, Martin, et al. “Algorithmic Solvability of the Lifting Extension Problem.” <i>Discrete &#38; Computational Geometry</i>, vol. 54, no. 4, Springer, 2017, pp. 915–65, doi:<a href=\"https://doi.org/10.1007/s00454-016-9855-6\">10.1007/s00454-016-9855-6</a>.","ista":"Čadek M, Krcál M, Vokřínek L. 2017.
