An arXiv preprint titled "On the number of edges in quasiplanar graphs" addresses a conjecture by Pach, Shahrokhi, and Szegedy. A k-quasiplanar graph is a graph drawn in the plane with no k pairwise crossing edges, and the conjecture states that every such graph on n vertices has O_k(n) edges. According to the abstract, ChatGPT produced a proof of this conjecture. The authors present a simplified, self-contained version of that proof.

AI-assisted summary based on the listed source.
A $k$-quasiplanar graph is a graph drawn in the plane with no $k$ pairwise crossing edges. Pach, Shahrokhi, and Szegedy conjectured that every such graph on $n$ vertices has $O_k(n)$ edges. ChatGPT produced a proof of this conjecture. Here, we present a simplified, self-contained version of that proof.
The source is a mathematics preprint, so its direct impact is on researchers in graph theory and combinatorics who study edge bounds for quasiplanar graphs. It is a concrete example of an AI system being credited with producing a proof for an open conjecture, which is relevant to people evaluating AI tools for research. Readers should look for independent peer review of the proof and whether the simplified version holds up under expert scrutiny.
VQV organizes public signals from inspectable sources. It does not independently verify the underlying report.
Signal Strength reflects source quality, relevance, freshness and evidence. Public Interest helps organize discovery; it is not proof of truth.
ChatGPT has a source-backed pricing with coverage spanning pricing.
VQV surfaced this signal because it is recent, relevant to Consumer AI, connected to arXiv.
