This is open in general. We prove that every graph with minimum degree $\\delta\\geq 10^6$ can be decomposed into two subgraphs requiring just weights $1$ and $2$ for the same goal. We thus prove the so-called Standard $(2,2)$-Conjecture for graphs with sufficiently large minimum degree. The result is in particular based on applications of the Lov\\'asz Local Lemma and theorems on degree-constrained subgraphs.", "revisions": [ { "version": "v1", "updated": "2019-11-03T11:12:19.000Z" } ], "analyses": { "keywords": [ "adjacent vertices receive distinct", "vertices receive distinct weighted degrees", "lovasz local lemma", "sufficiently large minimum degree", "conjecture asserts" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable" } } }
