“…For a uniform hypergraph G, bounds for the spectral radius ρ 0 (G) have been given in [1,13,15,30], and bounds for the signless Laplacian spectral radius 2ρ 1/2 (G) may be found in [6,13,23]. Recently, Lin et al [12] gave upper bounds for α-spectral radius of connected irregular k-uniform hypergraphs, extending some known bounds for ordinary graphs. Some hypergraph transformations have been proposed to investigate the change of the 0-spectral radius, and the unique hypergraphs that maximize or minimize the 0-spectral radius have been determined among some classes of uniform hypergraphs (especially for hypertrees), see, e.g., [3,5,7,18,25,26,29,32].…”
