We, complementing existing results, extend the Erd\\H{o}s-Gallai Theorem in random graphs. In particular, we determine, up to a constant factor, the extremal function in $G(N,p)$ for containing a path $P_n$, practically for all values of $N,n$ and $p$. Our work is also motivated by the recent progress on the size-Ramsey number of paths.", "revisions": [ { "version": "v1", "updated": "2019-08-31T13:48:51.000Z" } ], "analyses": { "keywords": [ "random graphs", "erdős-gallai theorem", "size-ramsey number", "random environment", "classical extremal theorems" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
