This was very recently extended to odd cycles in place of $K_3$ by Wang, Wang, Yang and Yuan. We further extend it to some other 3-chromatic graphs, and obtain some other stability results along the way.", "revisions": [ { "version": "v1", "updated": "2021-01-08T21:13:43.000Z" } ], "analyses": { "keywords": [ "free graphs", "stability results", "odd cycles", "partite subgraph", "edges contain" ], "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable" } } }
