Title: | Proofs of a few special cases of a conjecture on energy of non-singular graphsi | Journal: | Match | Volume: | 86 | Issue: | 3 | First page: | 577 | Last page: | 586 | Issue Date: | 1-Jan-2021 | Rank: | ~M22 | ISSN: | 0340-6253 | Abstract: | Akbari and Hosseinzadeh [MATCH Commun. Math. Comput. Chem. 83 (2020), 631{633] conjectured that the energy of a non-singular graph G is bounded from below by the sum of the maximum and the minimum vertex degree of G, with equality if and only if G is a complete graph. We discuss this conjecture here and provide a few lower bounds on the energy which prove this conjecture in several special cases. |
