We obtain our results using majorization methods and illustrate our findings in tables, diagrams, and curves. Keywords: Laplacian eigenvalues; wheel graph; Grone–Merris–Bai theorem; Brouwer’s conjecture; symmetry of wheel graphs; automorphism group of graphs...
𝑑𝛼-extremal) if it has diameter d and exactly 𝑑+1 distinct eigenvalues (resp. 𝛼-eigenvalues), and a graph is split if its vertex set can be partitioned into a clique and a stable set. Such graphs have a diameter of at most three. If all vertex degrees in a split graph ...
We find that four industries appeared for CSI163, which are finance and insurance, pharmaceuticals, machinery, and metals, whereas for S&P468, we find only three industries appeared, which are utilities, financials, and energy. This reveals the leading industrial sectors for the two markets over ...
