“…In [37] the spectral theory of undirected hypergraphs was presented via eigenvalues and eigenvectors of the adjacency tensor, Laplacian tensor, and signless Laplacian tensor. Recently a number of papers appeared in different aspects such as, spectral hypergraph theory [7,8,15,23,24,26,32,34,40,41,46,53], eigenvalues [17,25,33,42,43,44,45,48,50], connectivity [16,27], Laplacian tensor [1,18,20,35,37,51], structured tensors related [5,9], special hypergraphs [2,19,22,38,49],hypergraph properties [3,11,14,29,30].…”
