gives a list of authority and hub centralities for the vertices in the graph g.


uses rules vw to specify the graph g.

Details and Options

  • HITSCentrality gives two lists of authority centralities and hub centralities for each vertex.
  • If the graph g has adjacency matrix , then authority centralities are given by TemplateBox[{a}, Transpose].a.x=lambda_1 x, where is the largest eigenvalue of TemplateBox[{a}, Transpose].a, and hub centralities are given by . »
  • The authority and hub centralities satisfy and x=1/lambda_1TemplateBox[{a}, Transpose].y. »
  • The option WorkingPrecision->p can be used to control the precision used in internal computations.
  • HITSCentrality works with undirected graphs, directed graphs, multigraphs, and mixed graphs.
