We focus on conditions for the existence of almost r-embeddings, i.e., maps f : K → double-struck Rd such that f(σ1) ∩ ⋯ ∩ f(σr) = ∅ whenever σ1, ..., σr are pairwise disjoint simplices of K. Generalizing the classical Haefliger-Weber embeddability criterion, we show that a well-known necessary deleted product condition for the existence of almost r-embeddings is sufficient in a suitable r-metastable range of dimensions: If rd ≥ (r + 1) dim K + 3, then there exists an almost r-embedding K → double-struck Rd if and only if there exists an equivariant map (K)Δ r → Sr Sd(r-1)-1, where (K)Δ r is the deleted r-fold product of K, the target Sd(r-1)-1 is the sphere of dimension d(r - 1) - 1, and Sr is the symmetric group. This significantly extends one of the main results of our previous paper (which treated the special case where d = rk and dim K = (r - 1)k for some k ≥ 3), and settles an open question raised there.","lang":"eng"}],"publication_status":"published","alternative_title":["LIPIcs"],"_id":"1381","doi":"10.4230/LIPIcs.SoCG.2016.51","author":[{"first_name":"Isaac","full_name":"Mabillard, Isaac","id":"32BF9DAA-F248-11E8-B48F-1D18A9856A87","last_name":"Mabillard"},{"id":"36690CA2-F248-11E8-B48F-1D18A9856A87","last_name":"Wagner","orcid":"0000-0002-1494-0568","full_name":"Wagner, Uli","first_name":"Uli"}],"conference":{"start_date":"2016-06-14","end_date":"2016-06-17","location":"Medford, MA, USA","name":"SoCG: Symposium on Computational Geometry"},"month":"06","date_created":"2018-12-11T11:51:41Z","citation":{"short":"I.
