In particular, we study the appearance of a fixed subgraph in the trace. We prove that for a subgraph containing a cycle, the threshold for its appearance in the trace of a random walk of length $m$ is essentially equal to the threshold for its appearance in the random graph drawn from $G(n,m)$. In the case where the base graph is the complete graph, we show that a fixed forest appears in the trace typically much earlier than it appears in $G(n,m)$.", "revisions": [ { "version": "v1", "updated": "2016-05-15T18:03:56.000Z" } ], "analyses": { "subjects": [ "05C81", "05C80", "60G50" ], "keywords": [ "random walk", "small subgraphs", "complete graph", "appearance", "random graph drawn" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable" } } }
