Clustering is concerned with coherently grouping observations without any explicit concept of true groupings. Spectral graph clustering—clustering the vertices of a graph based on their spectral ...

Additionally, we found that other spectral features of the HVG could do a better job. Besides this, this paper is the first one that attempts to make a rigorous analysis of the spectral properties of ...

Abstract. In the present paper we are interested in the study of the distance Laplacian eigenvalues of a connected graph with fixed order n and chromatic number χ. We prove lower bounds on the ...
