VibeMathed record: Sombor-Energy Conjecture

specialist registry · passed

The proof has been internally audited using exact calculations. The graph has nine vertices, fifteen distinct edges and degree sequence $(4,4,4,3,3,3,3,3,3)$ . Its connectivity, bipartition, Sombor matrix, product $B^{T}B$ , singular values, complete spectrum and energy $64$ were independently recomputed within the AI conversation. The result has not yet been checked by an independent graph-theory expert, peer reviewer or formal proof assistant. A literature search located the original conjecture, the 2023 partial-results paper and its 2024 corrigendum, but did not locate an equivalent connected counterexample. This search does not establish absolute priority, and no claim is made that this is the first or a new counterexample.
