WebOn the spectral radii of trees, Journal of East China Normal University (Natural Science), 3: 22-28 (2004)] determined the first seven trees of order n with the smallest spectral radius. In this paper, we extend this ordering by determining the trees with the eighth to the tenth smallest spectral radius among all trees withn vertices. WebJul 31, 2024 · Recently, Yuan and Du [17] determined the bicyclic graphs of order with the first two maximum ABC spectral radii, which are exactly the unique two bicyclic graphs of order with maximum degree . The trees with the first few largest ABC spectral radii have been determined in [1], [15].
WebConsequently, the trees of order at least 10 with the 1st to 5th largest ABC spectral radii are determined. We wonder how the “Ruler Theorem” holds for ABC spectral radius of trees. Let G = ( V , E ) be a connected graph, where V = { v 1 , v 2 , …
