报告摘要：A signed k-graph is a signed k-uniform hypergraph with an incidence function oneach vertex and its incident edge. In this talk we extend some concepts of the adjacencyand Laplacian tensor from k-graphs to signed k-graphs. Based on the spectralproperties of the real symmetric tensor, we give some results about the H-spectrumof adjacency and Laplacian tensors for signed k-graphs. In addition, we present someproperties for the inverse Perron value. Finally some future works on signed k-graphsare given.
