We prove that in the $r$-uniform binomial random hypergraph $H^r(n,p)$, the order of the loose core undergoes a phase transition at a certain critical threshold and determine this order, as well as the number of edges, asymptotically in the subcritical and supercritical regimes. \r\nOur main tool is an algorithm called CoreConstruct, which enables us to analyse a peeling process for the loose core. By analysing this algorithm we determine the asymptotic degree distribution of vertices in the loose core and in particular how many vertices and edges the loose core contains. As a corollary we obtain an improved upper bound on the length of the longest loose cycle in $H^r(n,p)$.","lang":"eng"}],"issue":"4","file":[{"date_updated":"2023-01-30T11:45:13Z","success":1,"relation":"main_file","file_id":"12462","file_name":"2022_ElecJournCombinatorics_Cooley_Kang_Zalla.pdf","creator":"dernst","content_type":"application/pdf","access_level":"open_access","file_size":626953,"checksum":"00122b2459f09b5ae43073bfba565e94","date_created":"2023-01-30T11:45:13Z"}],"department":[{"_id":"MaKw"}],"publisher":"The Electronic Journal of Combinatorics","publication":"The Electronic Journal of Combinatorics","ddc":["510"],"day":"21","oa":1,"language":[{"iso":"eng"}],"title":"Loose cores and cycles in random hypergraphs","article_type":"original","doi":"10.37236/10794"}
