On a lower bound for the Laplacian eigenvalues of a graph
If μm and dm denote, respectively, the m-th largest Laplacian eigenvalue and the m-th largest vertex degree of a graph, then μm⩾dm−m+2. This inequality was conjectured by Guo (Linear Multilinear Algebra 55:93–102, 2007) and proved by Brouwer and Haemers (Linear Algebra Appl 429:2131–2135, 2008). Bro...
