We investigate under which conditions for $r$ the graph $G$ will a.a.s. contain the $k$-th power of a Hamilton cycle, for any choice of $H_n$. We provide asymptotically optimal conditions for $r$ for all values of $\\alpha$, $d$ and $k$. This has applications in the containment of other spanning structures, such as $F$-factors.", "revisions": [ { "version": "v1", "updated": "2022-05-18T14:52:50.000Z" } ], "analyses": { "keywords": [ "hamilton cycle", "dense graphs", "dimensional random geometric graph", "minimum degree", "th power" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
